Up-converting characteristics of Y203:Yb/Er nanocrystalline powders obtained through spray pyrolysis
(Univerzitet u Beogradu, Tehnološko-metalurški fakultet, 2012)
Sub-micronic, spherical Y203:Yb/Er particles comprising clustered nano-units were prepared through ultrasonic spray pyrolysis of pure nitrate precursor solutions that contain different Yb/Er dopants ratio (10, 5 and 2). ...
Synthesis of Cerium-Activated Yttrium Aluminate Based Fine Phosphors by an Aerosol Route
(European Journal of Inorganic Chemistry, 2012)
Polycrystalline fine powders of yttrium aluminate doped with Ce3+ were synthesised by spray pyrolysis of a polymeric precursor, which was obtained by dissolving the corresponding nitrates in a solution of ethylenediamine ...
Ho2O3 Additive Effects on Microstructure and Dielectrical Properties of BaTiO3 Ceramics
(Belgrade : Serbian Ceramic Society, 2012)
Doped BaTiO3-ceramics is very interesting for its application as resistors with PTCR, multilayer ceramics capacitors, thermal sensors etc. Ho doped BaTiO3 ceramics, with different Ho2O3 content, ranging from 0.01 to 1.0 ...
Up-conversion Luminescence in Ho3+ and Tm3+ co-doped Y2O3 :Yb3+ Fine Powders
(Belgrade : Serbian Ceramic Society, 2012)
Fine yttrium oxide powders doped with Yb3+ and co-doped either with Tm3+ or Ho3+ were synthesized via spray pyrolysis at 900 °C using 0.1 M nitrate precursor. Synthesized powders were additionally thermally treated at 1100 ...
Aerosol-assisted processing of Dopamine-TiO2 colloidal solution
(Belgrade : Serbian Ceramic Society, 2012)
Poster presented at the conference Advanced Ceramics and Application I - Serbian Ceramic Society, Belgrade May 10-11, 2012
Study of Dielectric Behavior and Electrical Properties of Hematite a-Fe2O3 Doped with Zn
(Belgrade : Serbian Ceramic Society, 2012)
The effects of Zn-doping on the dielectric behavior and electrical properties of bulk alpha-Fe2O3 have been studied. X-ray diffraction analysis revealed the presence of two phases in all samples: hematite and spinel ZnFe2O4, ...
Aerosol-assisted Processing of Dopamine-TiO2 Colloidal Solution
(Belgrade : Serbian Ceramic Society, 2012)
Set of colloidal TiO2 nanoparticles solutions (TiO2 NPs) were surface modified with the different quantities of dopamine (DA) and then are used as precursors for the synthesis of DA modified submicronic TiO2 particles ...
Kreiranje morfologije i veličine čestica ZnO prahova
(Beograd : Savez inženjera i tehničara Srbije, 2012)
U ovom tekstu objašnjeni su postupci sinteze prahova ZnO i mogućnosti da se tim sintezama morfologija i srednja veličina čestica kreiraju od mikrometarskih štapića do nanometarskih sfernih čestica. Primenjene su dve metode ...
Controlled hydrothermal processing of ZnO powders in the presence of PVP
(Society of Physical Chemists of Serbia, 2012)
In this study low-temperature hydrothermal processing was used for synthesis of ZnO powders with controlled morphology, from micro rods, via hexagonal prism-like to nano-spheres, by varying [Zn2+]/[OH-] molar ratio. The ...
Influence of Mechanical Activation on the Constituents of the MgO-Al2O3-SiO2-TiO2 System
(Belgrade : Serbian Ceramic Society, 2012)
Cordierite, 2MgO2Al2O35SiO2, is a very attractive high-temperature ceramic material, due to its outstanding electrical characteristics, such as the low temperature expansion coefficient, low dielectric constant and good ...
