AB  - Novel cotton-based TiO2/Ag/TiO2 nanocomposites for wastewater treatment were developed by fine chemical synthesis path with the goal of coping with wastewater issues and environmental remediation. The photocatalytic performances of nanocomposites were tested during photodegradation processes of RB, AO7 and MR under simulated solar light. Double- and single-loaded nanocomposites were synthesized by a simple bottom-up approach implying in situ photoreduction of Ag+ ions on the surface of TiO2 NPs previously deposited on cotton fibers from colloids. The spherical-like colloidal TiO2 NPs (4.5 nm) and TiO2/Ag NPs (8 nm) and the formation of uniform TiO2/Ag and TiO2/Ag/TiO2 nano-coatings on cotton fibers were examined by TEM and FESEM. The reduction of Ag+ ions on TiO2 surface was undoubtedly proven by the appearance of SPR band of Ag NPs in UV/Vis spectra. Raman spectroscopy clearly confirmed the presence of anatase TiO2 in nanocomposites. Quantitative determination of TiO2 and Ag in nanocomposites was accomplished using EDX and ICP–OES. The cotton-based TiO2/Ag/TiO2 nanocomposite showed the highest photocatalytic efficiency (> 90%) and maintained its removal efficiency after three reuse cycles, indicated its exceptional photochemical ability. The initial idea of improved photocatalytic performances of a TiO2 NPs double-layer with immobilized Ag NPs was justified as the TiO2/Ag/TiO2 processed sample contributed additional binding sites for dye molecules. Considering that the photocatalytic activity of the cotton-based TiO2 and TiO2/Ag samples was practically imperceptible, it can be assumed that the synthesized Ag NPs act predominantly as electron traps in the double-loaded synthesized system.

AB  - In this preliminary study, we applied the Multivariate Curve Resolution- Alternating Least Squares (MCR-ALS) method to analyze the excitation-emission matrices of multifloral honey samples, combined with differential scanning calorimetry (DSC) to estimate infection of honey bee colonies with N. ceranae or V. destructor. Fluorescence spectroscopy combined with MCR-ALS was used to determine the ratio of the spectral components originating from proteins (C1) and phenolics (C2), two minor but essential constituents of honey, as a ratiometric indicator of infection level in related hives. The C1/C2 ratio decreased linearly with the increase of infection in both N. ceranae and V. destructor cases, the R2 was 0.941 and 0.912, respectively. Additionally, DSC has shown that the magnitude of changes in sugar environments of the honey samples, reflected in sugar phase transitions, rises with increasing infection level in bee colonies. These results indicate that fluorescence combined with MCR-ALS could be used for rapid, non-destructive and cheap screening of honey to estimate the level of infection of honey bee colonies.

AB  - Nanopowders of up-conversion SrGd2O4 orthorhombic (Pnma) phase co-doped with different Yb3+ (1, 2.5 and 5 at%) and constant Er3+ (0.5 at%) ions were successfully prepared via sol-gel assisted combustion. Rietveld refinement indicated unit cell lattice parameters increase with Yb3+ and Er3+ ions doping. Scanning transmission electron microscopy with corresponding energy-dispersive X-ray spectroscopy revealed that obtained powders are composed of agglomerated nanoparticles that have a uniform distribution of all constituting elements. Photoluminescence measurements implied intensification of the up-conversion (UC) emission in the visible part of spectrum with the increase of Yb3+ content, which is followed by a significant change in the green to red ratio. Two-photon UC processes are established as a result of Er3+ f-f electronic transitions: green emission at 523 and 551 nm (2H11/2, 4S3/2 → 4I15/2) as well as a red emission at 661 nm (4F9/2 → 4I15/2). The highest value of absolute quantum yield of 0.055% is determined for SrGd2O4 nanoparticles doped with 0.5 at% of Er3+ and co-doped with 5 at% of Yb3+ (λexc = 976 nm, power density 200 W/cm2).

AB  - Primary seawater magnesium-based cell with AgCl or PbCl2 cathodes is widely used as power sources. In this paper, we consider the cyclic galvanostatic formation of silver and lead chlorides and their electrochemical behavior for potential applications in the new concept of the seawater quasi-rechargeable magnesium cell. For potential cells, the voltage for Mg alloy AZ63 and AgCl is ~ 1.5 V, and for the PbCl2, ~ 1 V. High discharge specific capacity, energy, and power are obtained under the very high discharge rate. It is also presented that systems could be potentially used in emergency situations for a few days up to a few weeks as a power source in the life-saving boat for sporadic emitting GPS-SOS tacking signals and night signal lights.

AB  - The aim of this work is in situ anodization/anaphoretic deposition of a nano amorphous calcium phosphate (ACP)/chitosan oligosaccharide lactate (ChOL) multifunctional hybrid coating decorated with selenium (Se) on a titanium substrate and in vivo investigation of its immunomodulatory and anti-inflammatory effect. Investigating phenomena at the implant–tissue interface of interest for controlled inflammation and immunomodulation was also the aim of the research. In our earlier research, we designed coatings based on ACP and ChOL on titanium with anticorrosive, antibacterial and biocompatible properties, while in the presented results we show that selenium addition makes this coating an immunomodulator. The immunomodulatory effect of the novel hybrid coating is characterized by the examination of the functional aspects in the tissue around the implant (in vivo): proinflammatory cytokines’ gene expression, M1 (iNOS) and M2 (Arg1) macrophages, fibrous capsule formation (TGF-β) and vascularization (VEGF). The EDS, FTIR and XRD analyses prove the formation of a ACP/ChOL/Se multifunctional hybrid coating on Ti and the presence of Se. A higher M2/M1 macrophage ratio in the ACP/ChOL/Se-coated implants compared to pure titanium implants (a higher level of Arg1 expression) is noted at all time points examined (after 7, 14 and 28 days). Lower inflammation measured by gene expression of proinflammatory cytokines IL-1β and TNF, lower expression of TGF-β in the surrounding tissue and higher IL-6 expression (solely at day 7 post-implantation) is noted in presence of the ACP/ChOL/Se-coated implants.

abstract = "The aim of this work is in situ anodization/anaphoretic deposition of a nano amorphous calcium phosphate (ACP)/chitosan oligosaccharide lactate (ChOL) multifunctional hybrid coating decorated with selenium (Se) on a titanium substrate and in vivo investigation of its immunomodulatory and anti-inflammatory effect. Investigating phenomena at the implant–tissue interface of interest for controlled inflammation and immunomodulation was also the aim of the research. In our earlier research, we designed coatings based on ACP and ChOL on titanium with anticorrosive, antibacterial and biocompatible properties, while in the presented results we show that selenium addition makes this coating an immunomodulator. The immunomodulatory effect of the novel hybrid coating is characterized by the examination of the functional aspects in the tissue around the implant (in vivo): proinflammatory cytokines’ gene expression, M1 (iNOS) and M2 (Arg1) macrophages, fibrous capsule formation (TGF-β) and vascularization (VEGF). The EDS, FTIR and XRD analyses prove the formation of a ACP/ChOL/Se multifunctional hybrid coating on Ti and the presence of Se. A higher M2/M1 macrophage ratio in the ACP/ChOL/Se-coated implants compared to pure titanium implants (a higher level of Arg1 expression) is noted at all time points examined (after 7, 14 and 28 days). Lower inflammation measured by gene expression of proinflammatory cytokines IL-1β and TNF, lower expression of TGF-β in the surrounding tissue and higher IL-6 expression (solely at day 7 post-implantation) is noted in presence of the ACP/ChOL/Se-coated implants.",

AB  - Novel cotton-based TiO2/Ag/TiO2 nanocomposites for wastewater treatment were developed by fine chemical synthesis path with the goal of coping with wastewater issues and environmental remediation. The photocatalytic performances of nanocomposites were tested during photodegradation processes of RB, AO7 and MR under simulated solar light. Double- and single-loaded nanocomposites were synthesized by a simple bottom-up approach implying in situ photoreduction of Ag+ ions on the surface of TiO2 NPs previously deposited on cotton fibers from colloids. The spherical-like colloidal TiO2 NPs (4.5 nm) and TiO2/Ag NPs (8 nm) and the formation of uniform TiO2/Ag and TiO2/Ag/TiO2 nano-coatings on cotton fibers were examined by TEM and FESEM. The reduction of Ag+ ions on TiO2 surface was undoubtedly proven by the appearance of SPR band of Ag NPs in UV/Vis spectra. Raman spectroscopy clearly confirmed the presence of anatase TiO2 in nanocomposites. Quantitative determination of TiO2 and Ag in nanocomposites was accomplished using EDX and ICP–OES. The cotton-based TiO2/Ag/TiO2 nanocomposite showed the highest photocatalytic efficiency (> 90%) and maintained its removal efficiency after three reuse cycles, indicated its exceptional photochemical ability. The initial idea of improved photocatalytic performances of a TiO2 NPs double-layer with immobilized Ag NPs was justified as the TiO2/Ag/TiO2 processed sample contributed additional binding sites for dye molecules. Considering that the photocatalytic activity of the cotton-based TiO2 and TiO2/Ag samples was practically imperceptible, it can be assumed that the synthesized Ag NPs act predominantly as electron traps in the double-loaded synthesized system.

AB  - In this study, we report the influence of vanadium oxide (VO), as a photosensitive component, on the photoactivity of TiO2 nanotubes (TNTs). A series of TNTs of varying tube diameter were synthesized by the anodization of titanium foils at different voltages, while vanadium oxide was deposited on TNTs by wet chemical deposition. An improvement in the optical properties of nanotubes was observed after the deposition of vanadium oxide. An improvement in the optical properties (redshift in UV-Vis spectra) of TNTs and TNT/VO was noted. The photocatalytic activity was improved with increasing tube diameter, while it was weakened after the deposition of VO. Furthermore, photoactivity was investigated in photodiodes based on TNTs or TNT/VO and single crystals of CH3NH3PbI3. The photoelectric measurement revealed that different TNT diameters did not influence the I-V characteristic of the photodiodes, while the deposition of VO improved the photocurrent for smaller TNTs.

AB  - Temperature- and humidity-sensing properties were evaluated of NixMg1-x spinel ferrites (0 ≤ x ≤ 1) synthesized by a sol-gel combustion method using citric acid as fuel and nitrate ions as oxidizing agents. After the exothermic reaction, amorphous powders were calcined at 700 °C followed by characterization with XRD, FTIR, XPS, EDS and Raman spectroscopy and FESEM microscopy. Synthesized powders were tested as humidity- and temperature-sensing materials in the form of thick films on interdigitated electrodes on alumina substrate in a climatic chamber. The physicochemical investigation of synthesized materials revealed a cubic spinel Fd3¯m phase, nanosized but agglomerated particles with a partially to completely inverse spinel structure with increasing Ni content. Ni0.1Mg0.9Fe2O4 showed the highest material constant (B30,90) value of 3747 K and temperature sensitivity (α) of −4.08%/K compared to pure magnesium ferrite (B30,90 value of 3426 K and α of −3.73%/K) and the highest average sensitivity towards humidity of 922 kΩ/%RH in the relative humidity (RH) range of 40–90% at the working temperature of 25 °C.

AB  - The maximization of the number of exposed edges of layered MoS2-type transition metal dichalcogenides of general formula MX2 (M = Mo, W; X = S, Se) is difficult yet meaningful way to improve their electrochemical and electrocatalytic performance. In this work, an all-solid ball milling method for simultaneous introduction of defects and their hybridization through binding of ammonia borane (NH3BH3) to defect sites of MX2 is demonstrated. The milling conditions leads to partial separation and nanosizing of MX2 layers, simultaneously extensively introducing defects (cracks, vacancies, strains, voids etc.), while the detailed analysis revealed the functionalization of the material by binding of NH3BH3 to defect sites, which results in highly improved electrocatalytic performance of thus obtained composites with respect to MX2 for hydrogen evolution reaction. The mechanochemical approach thus enables preparation of MoS2-type materials with improved, highly tunable activity, potentially relevant for energy conversion and storage.

abstract = "The maximization of the number of exposed edges of layered MoS2-type transition metal dichalcogenides of general formula MX2 (M = Mo, W; X = S, Se) is difficult yet meaningful way to improve their electrochemical and electrocatalytic performance. In this work, an all-solid ball milling method for simultaneous introduction of defects and their hybridization through binding of ammonia borane (NH3BH3) to defect sites of MX2 is demonstrated. The milling conditions leads to partial separation and nanosizing of MX2 layers, simultaneously extensively introducing defects (cracks, vacancies, strains, voids etc.), while the detailed analysis revealed the functionalization of the material by binding of NH3BH3 to defect sites, which results in highly improved electrocatalytic performance of thus obtained composites with respect to MX2 for hydrogen evolution reaction. The mechanochemical approach thus enables preparation of MoS2-type materials with improved, highly tunable activity, potentially relevant for energy conversion and storage.",

AB  - Collagen membranes are routinely used in oral surgery for bone regeneration. Despite their numerous advantages, such as stimulating bone growth, bacterial contamination still remains one of the disadvantages of membrane use. Thus, we assessed the biocompatibility and osteogenic and antibacterial properties of a collagen membrane (OsteoBiol) modified with chitosan (CHI) and hydroxyapatite nanoparticles (HApNPs). Attenuated total reflectance-Fourier transform infrared spectroscopy (ATR FT-IR), X-ray powder diffraction (XRD), and field emission scanning electron microscopy (FE-SEM) were performed for membrane characterization. Biocompatibility was assessed on dental pulp stem cells (DPSCs) by an MTT assay, while the osteogenic effect was assessed by an ALP activity assay and qPCR analysis of osteogenic markers (BMP4, ALP, RUNX2, and OCN). Antimicrobial properties were investigated by counting colony-forming units (CFUs) of Streptococcus mitis, Porphyromonas gingivalis, and Fusobaterium nucleatum on membranes and in the surrounding medium. Membranes showed no cytotoxicity. ALP activity was higher and ALP, BMP4, and OCN genes were up-regulated in DPSCs on modified membranes compared to unmodified membranes. The CFUs were reduced on modified membranes and in the medium. Modified membranes showed great biocompatibility and a high osteoinductive effect. Additionally, they showed antimicrobial and antibiofilm effects against periopathogens. It can be concluded that the incorporation of CHI and hydroxyapatite nanoparticles in collagen membranes may be advantageous to promote osteogenesis and reduce bacterial adhesion.

AB  - Liposome-encapsulated folic acid was incorporated into the films made from sodium carboxymethyl cellulose (CMC) (2 mas%) and a mixture of carboxymethyl cellulose and solagum (9:1 w/w) using the film-forming cast solution method. Histidine was used to increase solubility for folic acid in liposomes (1-5 mg/ml), and propylene glycol was used as a film plasticizer (2.6 mas%). The obtained films (50-60 µm tick) containing 3.12-20.19 mg of folic acid per gram of film are envisaged to be used as patches for transdermal delivery of folic acid. Therefore, some physical, mechanical, release and structural attributes of the films were scrutinized. Folic acid gave yellow color to the films and contributed to stronger chemical bonds which resulted in improved strength of the film. Liposomes prolonged the release of folic acid from films to 24 h without adverse effects on mechanical properties of the films, but degraded homogeneity of the films, which could be ascribed to its agglomeration within the film matrix as revealed by AFM. According to the release at pH 5.5, the film formulation based on a blend of CMC and solagum containing 3 mg/ml liposome-encapsulated folic acid is recommended from the point of view of release kinetics determined by its solubility.  Practical application: Folic acid is effective in reducing oxidative stress levels in the skin and neutralizing the harmful free radicals and is also essential for various metabolic reactions in the body. However, the limited solubility of folic acid linked with its poor absorption in an organism, low storage stability, short half-life upon oral consumption, specific food preferences of some people, extensive liver metabolism, and pregnancy-induced vomiting point to a large potential in transdermal usage of folic acid. This has motivated us to design new multicomponent polymer-lipid systems as an alternative solution to overcome some of these drawbacks. The results obtained for these multicomponent films pointed to their potential for prolonged release of folic acid to 24 h, which can also be useful for scientists interested in encapsulating similar poorly soluble compounds in CMC patches. The finding can be also valuable information for pharmaceutical manufacturers and scientists worldwide.

AB  - Solidification of the aluminum alloys takes place in heat-resistant refractory materials made of either metal or oxides that are stable at high temperatures. The significantly different thermal conductivities between metals and heat-resistant oxides cause solidification with significantly different cooling rates. In this work, we formed a secondary Al-8wt%Si-3wt%Cu alloy in a stainless steel mould, a thin-walled stainless steel cup, and a thick-walled zirconium oxide cup. The course of the formation of the solidified structure was monitored by immersed thermocouples, which enabled the computer analysis of the cooling curves. The parameters on which the cooling rate had the most significant influence are the undercooling values of the formation of primary aluminum crystals, the time of the growth of primary aluminum crystals and the total solidification time from the formation of the first solid crystals to the formation of a fully solidified structure. The Al-8wt%Si-3wt%Cu aluminum alloy formed in metal mould has a smaller grain size and consequently higher tensile strength, lower macro-porosity and less rough surface than the alloy formed in refractory oxide coatings. The examined heat-resistant refractory material influenced the formation of three basic micro-constituents in the Al-8wt%Si-3wt%Cu alloy in different time intervals, which led to the formation of a different microstructure, where the decision on the choice of material for the heat-resistant refractory material depends on the profitability of the entire process, the required quality of the external surfaces and required minimum strength of the final product.

Polyvinyl alcohol (PVA) and a combination of PVA with polyethylene glycol (PEG) added as a plasticizer, were introduced as polymer binders to improve the compaction of oxide mixtures. It has been done by forming a suspension of oxide mixture and varying the polymer solution concentration and composition. By evaporating the solvent, new materials were obtained, which consist of oxide particles bound via polymer. In such a manner obtained hybrid materials were characterized with attenuated total reflection Fourier transformed infrared (ATR-FTIR) spectroscopy, differential thermal analysis (DTA) and transmission electron microscopy (TEM). The oxide polymer material was compacted at 200 MPa and the expansion of this compact during heating was monitored in temperature range up to 550 ºC with dilatometer. It was found that PVA forms graft polymer with PEG and specific interaction with oxide particles surface was revealed.

AB  - Hydroxyapatite attracts great attention as hard tissues implant material for bones and teeth. Its application in reconstructive medicine depends on its biocompatibility, which is in a function of composition and surface properties. The insertion of a protein element in the composition of implants can improve the cell adhesion and the osseointegration. Having this in mind, the proposal of this work was to develop L-alanine-grafted hydroxyapatite nanoparticles and to study their biocompatibility. Two L-alanine sources and three grafting methods were used for hydroxyapatite surface functionalization. The efficiency of grafting was determined based on X-ray powder diffraction, Fourier-transform infrared spectroscopy, thermal analyses, and field-emission scanning electron microscopy. The results indicated the formation of hydroxyapatite with 8–25 wt% of organic content, depending on the grafting method. Protein adsorption, cell adhesion, and viability studies were carried out to evaluate biological properties of grafted materials. The viability of MG-63 human osteoblastic cells following 24 h incubation with the alanine-grafted hydroxyapatite samples is well preserved, being in all cases above the viability of cells incubated with hydroxyapatite. The alanine-grafted hydroxyapatite prepared in situ and by simple mixture showed higher protein adsorption and cell adhesion, respectively, indicating their potential toward use in regenerative medicine.

AB  - Sn-Pd electrocatalysts with a constant atomic ratio of 60 at.% Sn‒40 at.% Pd suitable for potential application in direct ethanol fuel cells were synthesized using a novel two-step electrodeposition method. First, Sn was electrodeposited in various forms of dendrites, from spear-like and needle-like to individual fern-like dendrites to a network of intertwined fern-like dendrites, by varying the cathodic potential and then performing electrodeposition of Pd at a constant current density in the second step. A morphological and elemental analysis of Sn and Sn-Pd electrocatalysts was performed using scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS) and X-ray photoelectron spectroscopy (XPS) techniques, while the size of Sn dendrites was analyzed using the particle size distribution (PSD) method. Cyclic voltammetry (CV) and chronoamperometry were applied in order to study the catalytic behavior of Sn-Pd electrocatalysts in the ethanol oxidation reaction (EOR), while CO stripping was used to estimate the antipoisoning capability of the electrocatalysts. The Sn surface morphology of the sub-layer was highly correlated with the electrocatalytic activity of the examined Sn-Pd electrocatalysts. The high activity it presented towards the EOR showed the suitability of the Sn-Pd electrocatalyst constructed from individual fern-like Sn dendrites as a sub-layer. Compared to Pd alone, this Sn-Pd catalyst showed more than 3 times higher activity and improved EOR kinetics. This enhancement in the catalytic activity of the Sn-Pd electrocatalysts is attributed to both the morphological characteristics of Sn as a sub-layer and the bifunctional effect.

AB  - Poly(vinylidenefluoride)–ZnO (PVDF–ZnO) nanocomposites with mechanically activated ZnO nanoparticle fillers were investigated using thermal and mechanical analysis and AFM and PFM. Differential scanning calorimetry (DSC) investigated the effect of ZnO nanoparticles on the crystallinity of the polymer, under controlled heating and cooling. Atomic force (AFM) microscopy was used to record the surfaces of the samples. Nanocomposite surface roughness shows the presence of the different phases inside of the matrix, where rough samples contain a higher proportion of the β phase. PFM was performed to investigate the piezoresponse of the composites. Nanoidentation showed that the mechanical activation of the filler (ZnO) increases the Young modulus with the activation time. Molecular simulations in periodic systems (PVDF–ZnO spherical nanocluster and nanocylinder composite) were used to investigate the influence of particle size and shape on the Young modulus of different phases of PVDF.

AB  - In recent decades, inorganic luminescent materials have gathered significant attention due to their great potential for various applications [1-4]. The rare-earth (RE)-based UC luminescent materials are particularly interesting for their exceptional optical, electronic, and magnetic properties. These materials have distinct intra-4f electronic transitions and existence of plenty long-living electronic excited states at different energies, all of which makes electron promotion to high-energy states possible [5, 6]. RE-based UC luminescent materials are composed of a host material (matrix), a sensitizer (absorbs the IC radiation), and an activator (provides emission in the visible and UV part of the spectrum) [7]. So far, the best results have been gained by co-doping the matrix using Yb3+ as sensitizer and Er3+, Ho3+, Tm3+, etc. as activators [8-10]. As for the hosts, rare-earth oxides (ARE2O4; A = Ca, Sr, Ba and RE = trivalent rare-earth ions) have great perspective for producing highly efficient luminescent materials. To the best of our knowledge, SrGd2O4 has been poorly investigated so far, although it has an enormous potential for variety of applications since it is environmentally friendly, has high thermal stability and good chemical durability [11]. In this work, we will present new UC luminescent material composed of SrGd2O4 (host) doped with Yb3+ (sensitizer) and Tm3+ (activator). Control of particle morphology has attracted a great deal of attention from researchers, so efforts for finding appropriate synthesis method are still very current issue. The morphology of the obtained particles is mostly influenced by the synthesis methods used for preparing the material. Luminescent properties mainly interested for us, are in very close connection with the morphology. Here, samples were synthesized using glycine-assisted combustion method, with constant concentration of Tm3+ (1 at%) and different concentration of Yb3+ (2, 4, 6 at%). All samples were heated in the furnace at 500 °C for 1.5h and then thermally treated for 2.5 h at 1000 °C. X-ray diffraction (XRD) was used to see phase crystallinity and purity, and revealed that all peaks are assigned to the pure orthorhombic lattice of SrGd2O4 with space group Pnma (JCPDS Card No.:01-072-6387). Luminescent properties were investigated after recording UC luminescence spectra at room temperature under 980 nm excitation for all samples. The spectra revealed strong blue emission bands which originates from Tm3+ ions 1D2 → 3F4 and 1G4 → 3H6 and weak red emission 1G4 → 3F4 transitions. Morphology and structure were thoroughly studied by field emission scanning electron microscopy (FE-SEM) and transmission electron microscopy (TEM), whilst energy dispersive spectroscopy (EDS) was used to provide additional information about constituting elements and their distribution. FE-SEM analysis revealed irregular spherical-like morphology with all samples, and particle size of around 100 nm. TEM examination showed nanostructures organized as a group of agglomerated nanoparticles. EDS verified uniform distribution of all composing elements through every sample [12].

AB  - The process where long-wavelength excitation radiation is converted into shorter wavelength output radiation is known as photon upconversion (UC). Research of up conversion materials is mainly focused on chloride, bromide, fluoride and oxide compounds doped with Pr3+, Nd3+, Dy3+, Ho3+, Er3+ and Yb3+ as activators [1]. Activators are incorporated in the form of rear earth elements (REE) at a proper position in the host lattice. The unique emission mechanism of REE is associated with the incompletely filled 4f shell which enables large numbers of sharp intra-4f electronic transitions and the existence of abundant, long-living electronic excited states. Oxides possess relatively low phonon energy, high thermal stability and admirable intrinsic luminescence properties compared to chlorides and fluorides as host crystal lattice [2,3]. Various host latticed and dopant metal ions have been implemented for obtaining new UC compounds and in our work we studied Ln2MoO6 (Ln=Y,Gd) and Sr2Gd2O4 doped with various concentrations of Yb3+ at constant Er3+ concentration. Synthesized powders were examined by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and luminescence emission and excitation spectroscopy. XRD analyses showed that SrGd2O4 single phase is obtained at 1100 °C, Gd2MoO6 phase starts to form at 750 °C and the pure phase is obtained at 900 °C, while Y2MoO6 was obtained at the lowest temperature of 600 °C. TEM analyses gave insight into particle size - powders obtained at lowest temperatures (Y2MoO6) have the smallest particle size in the range of ~10 nm (Figure 1a), while SrGd2O4 exhibited grain sizes in 150-200 nm range (Figure 1b). The EDS mapping confirmed presence of Yb3+, uniformly distributed in host lattice. Photoluminescence spectra of SrGd2O4 showed emission peaks that can be assigned to the trivalent Er3+ f-f electronic transitions in the following way: two green emission bands at 523 and 551 nm while the red emission band at 661 nm. Continual intensification of UC with the increase of Yb3+ content indicates that the SrGd2O4 host matrix easily accommodates high dopant concentration without quenching. Photoluminescence properties showed that co-doped Y2MoO6 has double emitting luminescence with green emission band at 546 and 560 nm (2H11/2, 4S3/2 → 4I15/2) and red emission band at 655 nm (4F9/2 → 4I15/2); Gd2MoO6 showed double emitting luminescence with two green emission bands at 525 and 546 nm as well as a red emission band at 657 nm. The green UC emission intensity increased gradually with the increment of Yb3+ ion concentration. In comparison, the optimal doping concentration for the red UC emission was found to be 2.5 at %, which was much higher than that of the green UC emission. While the change of Yb3+ ion concentration does not influence the band position, it led to the change of the emission intensity. Increase of Yb3+ concentration in the host lattice leads to change of the green to red ratio, showing the ability for fine-tuning of the color output. Therefore, these materials can be used in lasers and devices for optical communications because of the infrared-to-visible light conversion.

AB  - Dense calcium phosphate-based ceramics were fabricated to be used as targets for pulsed laser deposition (PLD). Nanostructured cobalt-substituted hydroxyapatite (Co:HAP) was used as a starting powder. To vary phase composition and microstructure of targets, two sintering approaches were applied, conventional (CS) and two-step sintering (TSS). The obtained results show that in both cases biphasic calcium phosphate (BCP) ceramics (targets) were prepared, with slightly different HAP-to-β–TCP amount ratio and a significantly different microstructure. While the CS method yielded fully dense ceramics with an average grain size of 1.3 μm, the ceramics prepared by TSS had a density of 98.5%, with a predominant grain size below 100 nm. (Ca + Co)P coatings were prepared by PLD of (Ca + Co)P targets. The temperature of the Ti substrate was adjusted to be 25 and 500 °C. The results show that the phase composition of (Ca + Co)P coatings depended on the phase composition of targets as well as on the temperature of the Ti substrate. The coating prepared at 25 °C using CS target consisted of three calcium phosphate phases, HAP, β–TCP and α–TCP; when the TSS target was used, the coating was biphasic, containing HAP and β–TCP. When the substrate was heated to 500 °C, regardless of whether the CS or the TSS target was used, the deposited coatings were composed of HAP and α–TCP. Due to different phase compositions, the (Ca + Co)P coatings deposited at 25 °C showed an improved hardness compared to those deposited at 500 °C. The obtained results confirmed that the phase composition, morphology and mechanical properties of 0.3 μm thick (Ca + Co)P coatings on a Ti substrate can be tailored by employing (Ca + Co)P targets with different microstructures, and also by varying the temperature of the Ti substrate during deposition experiments.
