Dielectric properties of BaTiO3 nanocrystals synthesized by ambient-condition-sol process at low temperatures

Preparation and luminescent properties of Eu- doped BaTiO3 thin films by sol–gel process

Eu-doped BaTiO3 thin films with a pseudo-cubic perovskite structure were successfully fabricated on magnesia substrates at low temperature by using a high-concentration sol–gel process, in which the newly developed gel-aging process on substrate was employed. Film microstructure, crystallinity, sintering properties and photoluminescence (PL) were investigated. The xerogel thin films exhibited s...

Characterization of Zr-doped TiO2 nanocrystals prepared by a nonhydrolytic sol-gel method at high temperatures.

Highly crystalline and surface-modified Zr-doped TiO(2) nanorods were successfully prepared using a nonhydrolytic sol-gel method that involves the condensation of metal halides with alkoxides in anhydrous trioctylphosphine oxide (TOPO) at either 320 or 400 degrees C. In addition, the interaction of the cross-condensation between the Ti and Zr species was studied by characterizing the morphologi...

THICKNESS AND TEMPERATURES EFFECTS ON STRUCTURAL PROPERTIES OF Mg-DOPED ZnO FILMS BY SOL-GEL PROCESS

The mixed oxide Zn1-xMgxO (x=0.01-0.2) were prepared by sol-gel synthesis using metal-organic precursors. Zn1-xMgxO films were grown on glass substrates using sol-gel deep and spin coating. Different thickness of films, annealed at various temperatures, were tried to observe the thickness and temperature effects on structural properties. The surface morphologies of all samples were characterize...
