Amorphous TiO2 thin films with and without the doping of ZnFe2O4 were prepared by radio frequency magnetron sputtering. The influence of post-deposition annealing on the structural and optical properties was studied. It was established that the anatase single phase exists between 250 degree(s)C and 800 degree(s)C in the TiO2 thin films, and between 450 degree(s)C and 650 degree(s)C in the TiO2 thin films with 2 wt% doping of ZnFe2O4. The absorption edge of TiO2 thin films with and without doping exhibits a blue shift with decreasing annealing temperature and the absorption edge of TiO2 doped with ZnFe2O4 has moved to visible spectrum range. The enhanced photoluminescence of the TiO2 films doped with ZnFe2O4 was found in comparison with pure TiO2 thin films at room temperature.
