AB  - Up-converting nanoparticles (UCNPs) with unique ability to convert NIR to VIS light (anti-Stokes process) have a wide application in optoelectronics, forensic, security labeling and biomedicine. Over the past few years different methods (like co-precipitation, thermal decomposition, hydro/solvothermal synthesis, etc.) are used for synthesis of β-NaYF4: Yb/Er phase, mainly from toxic organic precursors. In this work we explore conditions for stabilization of β-NaYF4: Yb/Er phase in nanoparticles applying sonochemistry synthesis of common inorganic precursor. The XRPD analysis showed that pure β phase is possible to obtained after 120 min of ultrasonification, while for shorter processing time (30-90min), cubic α-NaYF4: Yb/Er or orthorhombic YF3 : Yb,Er phase were founded too. The SEM and TEM analysis reveal presence of elongated nanoparticles self-assembled in spindles long up to 500 nm. Evolution of particle morphological and particle composition are analysed and correlated further with intensity of green emission (2H11/2,4S3/2→4I15/2) intensity measured under excitation of 978 nm.

AB  - Up-conversion is the optical property of materials which have ability to convert low energy photons (usually from infrared spectrum) into higher energy photons (from visible spectrum). Such compounds, usually lanthanide doped oxides or fluorides, have many applications in photoluminescence science and technology today. Currently, (β) NaYF4:Yb,Er polymorph is considered to be the most efficient up-converting material. Its synthesis usually includes the usage of toxic solvents, long-term heating, high pressures, controlled gas atmosphere, etc. The aim of this work was to utilize rarely applied sonochemical synthesis for the stabilization of (β) NaYF4:Yb,Er phase under mild and environmental friendly conditions. For this purpose, we performed ultrasonic treatment of common nitrate precursors and sodium fluorine for a different time. The obtained powders were analyzed in order to determine their phase composition and thermal stability, morphology, dopants distribution, particles surface purity and luminescent characteristics. Owing to this, the chemical and crystal phase transformations that occurred  in specified periods of synthesis time are explained in detail. Moreover, it was shown that obtaining of uniformly doped (β) NaYF4:Yb,Er mosocrystalline particles is possible after 2h of sonication.

CaCu3Ti4-xRuxO12: Crystal structure, electrical and magnetic properties

AB  - The CaCu3Ti4O12 belongs to the large ACu3B4O12 family of materials. Crystallographic A site is most often occupied by alkaline-earth metals or lanthanides, while B site is occupied by transition metals. The type of cations that build up the structure strongly affects the properties of these. The CaCu3Ti4O12 has been extensively studied due to its high dielectric permittivity stable over a wide temperature and frequency range (up to 105, for 100-600 K and 102–105 Hz). Because of such characteristics, it has promising application in microelectronics. However, it has been shown that differences in the crystal structure and electrical properties of dielectric ceramics and metallic electrodes, may cause an energy barrier and occurrence of stress on the ceramic-electrode contact which reduces dielectric permittivity. Such stress can be prevented by using dielectric and electrode materials with as much as possible similar crystal structure, especially unit cell parameters. This investigation dealt with detailed structural (XRPD, HRTEM, SAED), dielectric and magnetic study of CaCu3Ti4-xRuxO12 (CCTRO, x = 0, 1 and 4) materials. The results of structural refinement show that in cubic symmetry with space group Im3 , both titanium and ruthenium ions occupied crystallographic B site. Moreover, the variation in stoichiometry slightly affects the value of the unit cell parameters but changes electrical properties of studied material. Thus, substitution of even one atom of Ru in CaCu3Ti4-xRuxO12 unit cell is enough to change material properties from dielectric to conductor solving the problem of stress appearance on the contact layer of dielectric/electrode in capacitors.

The product shows leaf-like nanosheet morphology with thickness <30 nm and lengths <1 µm. Three lepidocrocite-like titanates (Imm2 space group) with similar a and c lattice parameters but different interlayer distances (b/2) were identified.

AB  - Morphology control in the (Na,H)2TinO2n+1 system has been achieved by introducing particle size as the key parameter during hydrothermal synthesis. The process is applied for the synthesis of TiO2-based nanofibers and nanotubes from natural rutile sand. The method is favorable for large-scale production due to the simple synthetic approach and the low-cost precursor used. The morphology of the final product is controlled through variation of the precursor particle size by mechanical milling prior to hydrothermal treatment. Hydrothermal alkali treatment of natural rutile sand without milling at 140 °C for 70 h resulted in the formation of nanofibers. Some portion of unreacted rutile coexisted in the reaction product. However, when the adequately milled precursor was used under the same condition, the unreacted material disappeared in the product, while the morphology of the product was changed from nanofibers to nanotubes. To the best of our knowledge tubular nanostructures of titanates have not been synthesized from rutile mineral sand yet. © 2009 American Chemical Society.

AB  - NaxFexTi2-xO4 a compound from the CaFe2O4 structure type group, was obtained via hydrothermal route at a temperature lower than 200  {ring operator}C for the first time. Natural ilmenite sand, a low cost reagent, was used as a precursor and reacted with 10 mol/l NaOH for 70 h to obtained high yield (92% wt) of NaxFexTi2-xO4 with x ∼ 0.76 - 0.79, as evaluated through the Rietveld refinement and quantitative phase analysis of X-ray powder diffraction data. Transmission Electron Microscopy showed that NaxFexTi2-xO4 appears in submicron to micron crystals with well-defined facets, growing along the [001] crystallographic direction, which means that the tunnels, a peculiarity of this crystal structure, are oriented along the direction of growth. © 2007 Elsevier Ltd.

abstract = "NaxFexTi2-xO4 a compound from the CaFe2O4 structure type group, was obtained via hydrothermal route at a temperature lower than 200  {ring operator}C for the first time. Natural ilmenite sand, a low cost reagent, was used as a precursor and reacted with 10 mol/l NaOH for 70 h to obtained high yield (92% wt) of NaxFexTi2-xO4 with x ∼ 0.76 - 0.79, as evaluated through the Rietveld refinement and quantitative phase analysis of X-ray powder diffraction data. Transmission Electron Microscopy showed that NaxFexTi2-xO4 appears in submicron to micron crystals with well-defined facets, growing along the [001] crystallographic direction, which means that the tunnels, a peculiarity of this crystal structure, are oriented along the direction of growth. © 2007 Elsevier Ltd.
