TiO2 and Mn0.2Ti0.8O2thin films were prepared by sol-gel process and their structural and optical properties were examined. The structural properties of samples were investigated by the X-ray diffraction (XRD) and auto force microscope (AFM). The XRD results showed that TiO2 thin film calcined at 650°C was anatase phase, and Mn0.2Ti0.8O2 thin films calcined at the same temperature was rutile. The AFM results of both samples showed quite a smooth surface. Optical properties of samples were examined by UV absorption spectrum. The absorption edge of Mn0.2Ti0.8O2 red-shifted.
