AB  - Micro and nanostructured brucite (Mg(OH2)) particles synthesized by hydrothermal method from solutions with high content of hydrazine (0.14 M) and nitrate (0.24 g) were compared with samples obtained from low hydrazine content (0.0002 M) and nitrate (0.12 g). The samples were heated at 180 °C for 4 h, 6 h and 12 h. XRD, TEM-HRTEM, SAED and image analysis techniques were used for the morphological and structural characterization. The effect of electron beam irradiation on the brucite dehydration was observed in atomic resolution images at 300 kV. Hexagonal crystals show differences in crystallinity, strains and kinetic of reaction. High hydrazine/nitrate samples have slightly larger crystals with better crystallinity, showing a strong preferential orientation. Rietveld refinements show how unit cell parameters are bigger in samples obtained with higher hydrazine/nitrate content, confirming also the preferential orientation along the 0 0 0 1 plane. Differences in the dehydration process show the rapid formation of a porous surface, the amorphised cortex or the presence of highly oriented strains in samples prepared from higher hydrazine/nitrate content. Conversely, crystals slightly smaller with randomly scattered defect surfaces showing the Mg(OH)2/MgO interphase in samples prepared with low hydrazine/nitrate content. Significant differences in the kinetic of reaction indicate how the dehydration process is faster in samples prepared with high hydrazine/nitrate content.

AB  - Global climate changes and the aroused environmentally-energy problems categorically moved the research efforts towards programmed processing of a novel class of hierarchical materials having well defined phase, compositional and morphological features. The synthesis based on the principles of the molecular design and integrative chemistry which includes the innovative aerosol and hydro(solvo)thermal nanotechnology routes, the building block assembling and hybridization, represent intelligent platform for the creation of advanced functional materials. Due to exceptional optical properties and a diverse application in electronics, optoelectronics, energy conversion/storage and biomedicine, the examples from some wide band gap oxides for light harvesting and photocatalytic applications as well as both down and up-conversion energy-saving luminescent materials for photonic and biological applications are considered. With the help of various analyzing techniques like XRPD (X-ray powder diffraction), field emission scanning electron microscopy (FE-SEM), energy dispersive spectroscopy (EDS), analytical and high resolution transmission electron microscopy (TEM, HR-TEM), selected area electron diffraction (SAED), scanning tunneling electron microscopy (STEM), Fourier transform infrared (FTIR) and Raman spectroscopy, photocatalytic and fluorescence measurements, the opportunities of the aerosol and hydro(solvo)thermal routes for the synthesis of novel hierarchically and hybrid assembled structures and nanocomposites are reviewed highlighting the recent research activities realized in the Institute of Technical Sciences of SASA, Belgrade, Serbia and University Carlos III, Madrid, Spain. The morphological, structural and functional aspects of the following systems: ZnO, TiO2, Y2O3:Eu,Yb/Er/T/Hm, Y2O3:Eu@Ag, (Y1−xGdx)2O3:Eu, (NaYF4:Yb/Er)@EDTA/PEG/PVP, are discussed from the state-of-the art and literature contexts. Controlled growth of 1D and 3D hierarchical structures based on the single-source processing methodology in combination with the homogeneous precipitation of optically active intermediate precursor are especially stressed for the case of yttria based phosphor particles and phase-dependent luminescence efficiency. The obtained results offer possible routes for the synthesis of hierarchically structured nanomaterials with tunable structure, morphology and optical properties.

AB  - Hierarchically assembled TiO2 nanoparticles into larger spherical ones were obtained using aerosol-assisted processing method. Unagglomerated particles with the mean size of 440 nm were obtained from colloidal solution of TiO2 nanoparticles (~4.5 nm) using ultrasonic spray pyrolysis at 550°C. Their morphological complexity and structural polymorphism were investigated by using X-ray powder diffraction (XRPD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS) and transmission electron microscopy (TEM) coupled with selected area electron diffraction (SAED) analysis. Pronounced evolution of nanocrystalline TiO2(B) phase assembled together with the anatase building units (sized ~15 nm) in uniform submicrometric particles implicate their feasibility to be used in dye-sensitised solar cells and lithium ion batteries.

AB  - In the area of nanotechnology, which is one of the most active research fields, well-known functional material (ZnO) generates enormous scientific interest owing to its extraordinary properties and so, its novel applications at the nanometric scale. Besides the ZnO properties and its applications, its photocatalytic behavior has been widely studied. Currently, many works are focused on developing of hybrid materials of noble metal-doped ZnO to improve its catalytic activity. With this aim, using silver or platinum nanoparticles on the surface of nanoparticles could be a suitable option. So, in our study, synthesis (by solvothermal method) and characterization (structural, chemical, morphological among others) of ZnO nanostructured particles with silver or platinum nanoparticles (ZnO&Ag/Pt) have been developed. Afterward, the photocatalytic behavior has been evaluated. The best photocatalytic results (>60 % pollutant removal) demonstrate the viability for its application in the degradation of contaminants in water and, so, prove that the system morphology is critical to the properties of the obtained material.

AB  - Controlled magnesium hydroxide particles were successfully synthesized via a simple hydrothermal method. The influence of temperature and reaction time on the hydrothermal synthesis of Mg(OH)(2) was studied. The results provide new parameters to control the morphologies, particle sizes, agglomeration level and crystallographic structures of the brucite nanosized. The physic chemical properties of synthesized Mg(OH)(2) nanoparticles have been characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) combined with selected area electron diffraction (SAED), high resolution transmission electron microscopy (HR-TEM) and thermogravimetry/differential scanning calorimetry (TG/DSC). It has been shown that the prolongation of reaction time improves the crystalline degree of magnesium hydroxide particles. It was also possible to detect a relevant increase in the degree of crystallinity and a faster crystal growth with defined hexagonal morphologies in the samples obtained at higher temperature. Our results show that this simple hydrothermal route is highly interesting for the large scale production of these nanomaterials. (C) 2014 Elsevier Ltd and Techna Group S.r.l. All rights reserved.

AB  - In this research, we report the preparation and characterization of SnO2thin films preparation by the Ultrasonic Spray Pyrolysis technique using different fluorine content dissolved in ethanol as precursor solution, for its possible application as TCO's. The structural, optical and electric properties of synthesized SnO2:F films have been characterized by X-ray Diffraction (XRD), Profilometer, UV - Vis-NIR spectroscopy and electrical measurements by Hall Effect. Also structural changes were studied by X-ray diffraction. The main results show that the electrical resistivity of the films decreased with the fluorine content. The best electro-optical properties (electrical resistivity of 4.14x10-4O-cm and average transmittance of 80 [%]) were achieved in a fluorine content in relative with tin of about 0.52. Furthermore, a systematic change was observed in the intensity of the lines of the diffraction maxima of X-rays in function of fluorine content. ©Sociedad Mexicana de Ciencia y Tecnología de Superficies y Materiales.

AB  - In this work is reported the solvothermal synthesis of hybrid nanostructured ZnO&Ag systems starting from zinc nitrate hexahydrate (Zn(NO3)2•6H2O) and silver nitrate (Ag(NO3)2) as precursors. The structural and morphological properties of the obtained hybrid materials were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Subsequently, the photocatalytic behavior of prepared systems was evaluated. The results verify the viability of as-synthesized ZnO&Ag nanocomposites for its application in the removal of contaminants in water. The best results (percentage of pollutant removal > 99 %) are obtained for samples synthesized at low temperature, intermediate times, higher ratios Ag+/Zn2+ and in the presence of CTAB, which controls the final morphology of nanostructures and the dispersion thereof. These results prove that the system morphology is critical to the properties of the obtained material.

AB  - The interest in the nanostructured magnesium hydroxide (Mg(OH)2) is rapidly growing due to the fact that its physical and chemical properties makes it appropriate for multiple applications. So far, it has been used in medicine, industry, or more recently, in the conservation of cultural heritage. The current research is based on the synthesis and the characterization of functional and nanocrystalline Mg(OH)2 with different particle sizes, morphologies and high purity. The synthesis was carried out via the hydrothermal method using hydrazine hydrate as a precipitator. Moreover, due to it is essential to study the behaviour of this type of nanoparticles under factors as the time of exposition, the relative humidity and CO2 concentration, they were exposed to controlled atmosphere at high relative humidity (75%RH). The carbonation process was also studied, identifying the different magnesium carbonate polymorphs.The physical and chemical property of synthesizedMg(OH)2 nanoparticles have been characterized by X Ray diffraction (XRD), Scanning electron microscopy (SEM), Transmission electron microscopy (TEM), High resolution Transmission electron Microscopy (HR-TEM), thermogravimetry (TG) and differential scanning calorimetry (DSC). The results showed the successful use of this synthesis route to obtain Mg(OH)2 nanostructured with important properties for the preservation of the stone heritage and promising CO2 adsorption properties.

AB  - Sub-micronic particles are of considerable interest for a wide variety of applications, such as catalyst or optical ceramics, due to their unique properties determined by size, composition and structure. In this work, we have reported a simple, rapid, single-step aerosol processing for the continuous synthesis of nanostructured particles having homogeneous composition and narrow size distributions, good crystallinity and fluorescence response. This paper presents the synthesis, optimization and characterization of hybrid Ag@Y2O3:Eu (9 at.% Eu3+) phosphor particles by means of spray pyrolysis method from water solutions of common nitrates precursors. The effect of silver concentration on particle structure, morphology and functional properties was specially evaluated. The as-prepared samples were additionally heated from 800 to 1200 °C/12 h under constant argon flow to avoid the silver oxidation. It was evident the cubic phase with Ia-3 symmetry as the principal one in all as-prepared and thermally treated samples. For the case high silver nitrate concentrations in precursor solutions a minority crystalline phase having Fm3m symmetry was identified. The luminescence emission spectra have been taken after excitation at 235 nm wavelength. It is evident the increase in the emission caused by the presence of metallic silver nanoparticles onto Y2O3:Eu3+ particle surface. It was also determined the silver concentration influence on the fluorescence response.

The influence of temperature and reaction time on the hydrothermal synthesis of Mg(OH)2 was studied. The results provide new parameters to control the morphologies, particle sizes, agglomeration level and crystallographic structures of the brucite nanosized. The physic–chemical properties of synthesized Mg(OH)2 nanoparticles have been characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) combined with selected area electron diffraction (SAED), high resolution transmission electron microscopy (HR-TEM) and thermogravimetry/ differential scanning calorimetry (TG/DSC). It has been shown that the prolongation of reaction time improves the crystalline degree of magnesium hydroxide particles. It was also possible to detect a relevant increase in the degree of crystallinity and a faster crystal growth with defined hexagonal morphologies in the samples obtained at higher temperature. Our results show that this simple hydrothermal route is highly interesting for the large scale production of these nanomaterials.

With these techniques it has been possible to confirm the hollowness and porous nature of samples subjected to low temperature annealing (900 °C). Moreover, the beginning of the densification and sintering processes in samples subjected to thermal treatment at higher temperature (1100 °C) have been evaluated. Chemical analysis by electron energy loss spectroscopy (EELS) and X ray energy dispersive spectroscopy (EDS) carried out in STEM mode have allowed to confirm the high uniformity and the expected chemical composition. The high resolution tools either allowed to confirm the presence of a cubic (Ia3 symmetry) and the monoclinic (c2/m symmetry) phases in the nanostructured particles.

AB  - Global warming, climate change and natural resources depletion forces tremendous technological and scientific research activities for the development of next generation of materials able to address both the energy and environmental problems. This implies an exciting progress in the field of nanoscience and nanotechnology, particularly regarding the control synthesis of nanoscaled materials that might have a great potential for use in solid-state functional materials and devices, like phosphors, sensors, photovoltaics, catalysts, drug delivery carriers etc. The feasibility of the dispersion phase-aerosol route for the generation of innovative nanomaterials having advanced optical properties for solving energy/environmental problems is here presented. Particularly, the opportunities of the hot wall aerosol processing, provided by high heating and cooling rates, short residence time and high surface reaction, is demonstrated for the synthesis of spherical three-dimensional (3D), hierarchically organized nanostructured particles with uniformly distributed components and phases. The particles composite inner structure, representing an assembly of nanosized primary particles, opens the possibility for particle surface modification and functionalization emphasizing their application in photovoltaics, energy transfer and bioimaging. The diverse levels of structural, morphological and timctional complexity are explored by means of appropriate selection of different precursor solutions, either true or colloid, surface modification and proper selection of rare-earth based dopants for the generation of either photocatalytic titanium (IV) oxide or Yb3+, Er3+, codoped yttrium(III) oxide-based phosphor particles. Their advanced optical properties as the consequence of the particle nanostructure uature are proved by using various characterization techniques like x-ray powder diffraction (XRPD), scanning electron microscopy (SEM, FE-SEM), analytical and high-resolution transmission electron microscopy (TEMIHR-TEM) in combination with energy dispersive x-ray analysis (EDAX), selected area electron diffraction (SAED) and nanotomography. The optical properties and surface structure were analyzed by UV-Vis diffusive reflectance (UV-Vis DRS), Fourier transform infrared (FTIR) spectroscopy and by fluorescence measurements in the near infrared region. The obtained results offer ageneral route for the synthesis of nanomaterials with tunable structure, morphology and optical properties.

AB  - Nanotechnology is an emerging science involving synthesis and optimization of matter at the nanometer scale. The recent rise in the interest surrounding nanotechnology stems from its potential to revolutionize such fields as engineering and medicine. Nanoparticles, the building blocks of nanotechnology, have been broadly defined as having at least one dimension at 100 nm or less. Engineered nanoparticles are particles synthesized to exploit the size-related properties inherent in the nanoscale (e.g. conductivity, spectral properties, electrochemical properties, ... Spray pyrolysis is a versatile process regarding the powder synthesis of inorganic material. An atomizer (such as ultrasonic) is used to generate a mist from a water or organic solution of inorganic salts or metal organic compounds. The advantages of this method are that the control of particle size, particle size distribution, morphology, crystallite structure and chemical composition are possible. On the order hand, the hydrothermal synthesis is a useful method to prepare nanomaterials with homogeneous crystal structure and morphology, which has some advantages such as simple synthesis process and low energy consumption. In this work, different morphologies of zinc oxide (ZnO), including microrods, microspheres, hexagonal microprism, nanosheets or flower like have been obtained depending on what experimental conditions and synthesis method have been used. Also, hollow and spherical Ag/Y203:Eu (9% at) hybrid nanostructured particles by means of aerosol route from common nitrate solutions at 750°C in Ar atmosphere has been obtained. These as-prepared samples were additionally heated at temperatures up from 800° C to 1200 °C for 12h in argon atmosphere. The microstructures, morphologies and optical and functional properties of the as-prepared and heated samples were investigated by X-Ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HR-TEM), UV-VIS spectroscopy.
The photocatalytic activity of ZnO synthesized by different methods and experimental conditions was evaluated by removal rate of methyleneblue under UV irradiation (365 nm) at room temperature. The results showed that the photocatalytic efficiency of ZnO particles was enhanced by increased precursor concentration. In the case of Ag/Y203 systems, the luminescence results reveal a huge rise in the final luminescence properties as consequence of the "mirror effect" due to the presence of Ag nanoparticles.

Posteriormente, las partículas nanoestructuradas obtenidas se sometieron a distintos tratamientos térmicos comprendidos entre 800 y 1000ºC/12h en atmósfera de aire.
Las partículas obtenidas se caracterizaron mediante técnicas de DRX, SEM, dispersión láser y medidas de fluorescencia en estado estacionario.
Se ha podido identificar la existencia de dos fases cristalinas cúbicas con distinta simetría (Ia-3 y Fm-3m) en las muestras “as-prepared”. Además, se ha demostrado la presencia de una fase de Gd2O3 monoclínica (C2/m), la cual desaparece con los tratamientos térmicos posteriores. En todas las muestras tratadas térmicamente se observa la estabilización de la fase cúbica más estable con simetría Ia-3.

AB  - The processing of europium-doped gadolinia (Gd2O3:Eu) nanostructured particles has been realized using the bottom-up chemical approaches either by a hot-wall spray pyrolysis technique (SP), starting from the aerosol of common nitrates precursors, or a high energy ball milling (HEBM) of acetate precursors. The former one yields high-purity nanostructured nonagglomerated particles having spherical morphology and high chemical homogeneity. The HEBM-derived particles are with irregular morphology, submicronic in size, having an amorphous structure after 12h of milling. The detailed study of the crystalline structure and luminescent properties were proceeded for the different europium concentrations (1, 2 and 6at%) by means of XRPD, SEM, DSC, FTIR and steady state-fluorescent spectroscopy. The phase development and structural changes, followed by Fullprof program, implied the nanocrystalline inner structure (crystallites < 20 nm) and the coexistence of the following crystal phases for as-synthesized SP samples: two cubic phases, having either a bcc (SG: Ia3) or a fcc (SG: Fm-3m) structure, and a monoclinic phase with the space group (SG) C2/m. In the cubic Ia3 phase the cell parameter was affected by the europium concentration and the thermal treatment temperature, followed with progressive increase in crystallite size. On the other side, the monoclinic phase concentration decreased after additional thermal treatments. Luminescence measurements have detected the presence of divalent europium near to 480 nm, aside to the typical trivalent europium spectra. This behavior could explain the increase in the emission intensity in the blue spectral region due to the divalent europium.

AB  - Red emitting Y2O3:Eu3+ (5 and 10 at.%) submicronic particles were synthesized through ultrasonic spray pyrolysis method from the pure nitrate solutions at 900 °C. The employed synthesis conditions (gradual increase of temperature within triple zone reactor and extended residence time) assured formation of spherical, dense, non-agglomerated particles that are nanostructured (crystallite size ∼20 nm). The as-prepared powders were additionally thermally treated at temperatures up to 1200 °C. A bcc Ia-3 cubic phase presence and exceptional powder morphological features were maintained with heating and are followed with particle structural changes (crystallite growth up to 130 nm). Emission spectra were studied after excitation with 393 nm wavelength and together with the decay lifetimes for Eu3+ ion 5D0 and 5D1 levels revealed the effect of powder nanocrystalline nature on its luminescent properties. The emission spectra showed typical Eu3+ 5D0 → 7Fi (i = 0, 1, 2, 3, 4) transitions with dominant red emission at 611 nm, while the lifetime measurements revealed the quenching effect with the rise of dopant concentration and its more consistent distribution into host lattice due to the thermal treatment. © 2010 Elsevier B.V.

Structural and morphological analyses done by X-ray powder diffraction (XRPD) and transmission electron microscopy analysis (TEM) implied the formation of non-aggregated spherical, submicronic particles with smooth particle surfaces and filled morphology. The phase development and structural changes, determined using the Topas program, implied a nanocrystalline inner structure (crystallites &lt; 20 nm), that was also confirmed by SAED analysis. A bcc Ia-3 cubic phase was identified in all as-prepared samples, apart from the mixed oxide with the gadolinium content &gt; 75%, where the existence of a secondary, fee Fm-3m cubic phase is determined. Only Ia-3 cubic phase was identified in thermally treated samples (1100 °C), while the powder morphological features were maintained, followed by increase in powder crystallinity and phase homogeneity. Functional properties were analyzed by means of photoluminescent analysis. Emission spectra showed typical Eu 3+ 5D0→7Fi (i = 0, 1, 2, 3, 4) transitions with the dominant red emission peak at 611 nm.

This study presents the preparation and characterization of nanostructured spherical alumina particles by the Spray Pyrolysis method for the application in reinforcements of metal-matrix composites (MMCs). Synthesis procedure includes aerosol formation ultrasonically from alumina nitrate water solution and its decomposition into a tubular flow reactor at 700 °C. The obtained particles are spherical, smooth, amorphous and in non-agglomerated state. Microstructural and morphological analyses were carried out using X-ray diffraction (XRD), scanning electron microscopy (SEM/EDS) and analytical and high resolution transmission electron microscopy (TEM/HRTEM).

AB  - The diversity and potentials of the aerosol route for making functional materials at the nano size level are reviewed. Among the methods currently used for nanophase processing, synthesis through dispersion phase (aerosol) enables generation of ultrafine, either single or complex powders with controlled stoichiometry, chemical and phase content provided by high surface reaction, high heating and cooling rates and short residence time. It represents a "bottom-up" chemical approach and provides control over a variety of important parameters for particle processing. This may favors to the formation of either amorphous, nanocrystalline or metastable phases implying a huge impact in the search for advanced functional materials having novel and unique structures and properties. Particularly, the opportunities of the hot wall aerosol synthesis, i.e. spray pyrolysis, for the generation of ultrafine spherical particles with uniformly distributed components, phases and nano-clustered inner structure and luminescence properties is demonstrated with various analyzing tecniques like XRPD, FE-SEM, HR-TEM, STEM and nanotomography. Following the initial attempts, a more detailed aspect of the several phosphor particles generation based on Gd2O3:Eu, Y2O3:Eu, (Y1-xGdx)2O3:Eu and Y3Al5O12:Ce is reviewed highlighting the research activities in the Institute of Technical Sciences of SASA, Serbia. © 2009 Hosokawa Powder Technology Foundation.

Such properties are improved with the use of nanostructured materials with spherical geometry and narrow particle size distribution. Besides, luminescent properties enhance with a homogeneous distribution of dopant centers in the host matrix material. In this paper the synthesis and characterization of gadolinium and yttrium doped with different proportions of Europium are shown. Nanostructured particles were synthesized through Spray Pyrolysis route in a tubular furnace at different temperatures, and subjected to different post-thermal treatments. Scanning electron microscopy (SEM-EDS), transmission electron microscopy (TEM) and X-ray diffractometry (XRD) were used for the morphological, chemical and structural characterization of the nanoparticles.

AB  - Y2O3 doped with europium is a well known red  phosphor material employed in modern high-resolution display devices such as plasma display panels (PDP) and  field emission displays (FED). The incorporation of gadolinium in the yttria matrix may significantly contribute to the luminescent properties and x-ray absorption coefficient thus increasing the field of application in optoelectronic devices such as ceramic scintillators for computed tomography. In this work, the nanostructured particles of Y 2 O 3 doped with Eu 3+ were processed through the spray pyrolysis method. Synthesis was carried out with  an ultrasonic aerosol device operating at 1.3 MHz in air  atmosphere connected with a triple-zone tubular flow reactor (473-973-1173K). Particles were submitted t o post- thermal treatments at temperatures among 1273 and 1 573K for 12 hours in order to increase the crystallinity and uniform distribution of doped centers. Morphology, structure, crystallinity and chemical characteristics were  studied by XRD, SEM-EDS, TEM-HRTEM and SAED. The particles obtained are spherical, having narrow size distributions, high compositional homogeneity and are in unagglomerated state. The effects of synthesis parameters were followed and discussed in terms of particle structure and morphology.

abstract = "Y2O3 doped with europium is a well known red  phosphor material employed in modern high-resolution display devices such as plasma display panels (PDP) and  field emission displays (FED). The incorporation of gadolinium in the yttria matrix may significantly contribute to the luminescent properties and x-ray absorption coefficient thus increasing the field of application in optoelectronic devices such as ceramic scintillators for computed tomography. In this work, the nanostructured particles of Y 2 O 3 doped with Eu 3+ were processed through the spray pyrolysis method. Synthesis was carried out with  an ultrasonic aerosol device operating at 1.3 MHz in air  atmosphere connected with a triple-zone tubular flow reactor (473-973-1173K).
