Multisite luminescence of rare earth doped TiO2 anatase nanoparticles
(Materials Chemistry and Physics, 2012)
Eu3+, Sm3+ and Tb3+ ions have been incorporated into anatase TiO2 nanocrystals via hydrolytic sol gel method. Pure anatase phase was confirmed with XRD and TEM measurements. Band gap energies change slightly with rare earth ...
Electronic structure and optical properties of CuWO4: An ab initio study
(Computational Materials Science, 2012)
Electronic structure and optical properties of copper tungstate CuWO4 were investigated using density functional theory with improved version of exchange potential suggested recently by Tran and Blaha (2009)  (TB-mBJ). ...
Surface modification of submicronic TiO2 particles prepared by ultrasonic spray pyrolysis for visible light absorption
(Journal of Nanoparticle Research, 2012)
Spherical, submicronic TiO2 assemblage with high specific surface area and controllable phase composition was prepared in the process of ultrasonic spray drying/pyrolysis in a wide temperature range (150-800 degrees C) by ...
Fabrication of polycrystalline (Y0.7Gd0.3)(2)O-3:Eu3+ ceramics: The influence of initial pressure and sintering temperature on its morphology and photoluminescence activity
(Ceramics International, 2012)
Nanocrystalline (Y0.7Gd0.3)(2)O-3 powder, synthetised via polymer complex solution method, was compacted into 25 pellets applying high pressures (173-867 MPa) for 30 s that were subsequently sintered at different temperatures ...
Structural and optical characteristics of silver/poly(N-vinyl-2-pyrrolidone) nanosystems synthesized by gamma-irradiation
(Radiation Physics and Chemistry, 2012)
Silver nanoparticles (AgNPs) were synthesized in situ by gamma-irradiation using poly(N-vinyl-2-pyrrolidone) (PVP) as a capping agent. The concentration, molecular weight and the structure (crosslinked and interpenetrated ...
