TiO2and Ag+-doped TiO2thin films were successfully obtained on microscope glass slides by means of sol-gel method. Then the photocatalytic activity of the TiO2and Ag+-doped TiO2thin films was evaluated by the degradation of rhodamine B dye solution. The effects of both annealing temperatures and Ag+contents on the photocatalytic activity of TiO2thin films were examined. The results indicated that the TiO2thin films with an atomic ratio of Ti:Ag=10:1 annealed at 300°C had a higher photocatalytic activity.

TiO2 and different contents Fe3+-doped TiO2 thin films were successfully obtained on microscope glass slides by Sol-Gel method. Then the photocatalytic activities of the samples were evaluated by the degradation of Rhodamine B dye solution. The effects of both annealing temperatures and Fe3+ contents on the photocatalytic activities of TiO2 thin films were examined. The results indicated that the sample with an atomic ratio of Ti:Fe=7:3 annealed at 500°C had a higher photocatalytic activity.

Photocatalytic Activities

A series of TiO2 thin films with and without Ce3+ doping were successfully obtained on microscope glass slides by sol-gel method. The photocatalytic activities of the pure TiO2 and Ce3+-doped TiO2 thin films were evaluated by the degradation of rhodamine B solution. The effects of both Ce3+ contents and annealing temperatures on the photocatalytic activities of the samples were examined. The results indicated that the TiO2 thin film with an atomic ratio of Ti:Ce=5:1 annealed at 300°C had a higher photocatalytic activity among the samples.

Dielectric, Optical properties and microstructures of Mg(Zr0.05Ti0.95)O3 thin films prepared by sol-gel method on n-type Si(100) substrates at different annealing temperatures have been investigated. The selected-area diffraction pattern showed that the deposited films exhibited a polycrystalline microstructure. All films exhibited Mg(Zr0.05Ti0.95)O3 peaks orientation perpendicular to the substrate surface and the grain size with the increase in the annealing temperature. A dielectric constant of 7.4 and an optical bandgap of 3.7 were obtained for the prepared films.
