This paper presented the preparation of TiO2 thin film on empty glass and Indium Tin Oxide (ITO) glass by spin coat-ing method. Highly transparent titanium oxide thin films were obtained. The Optical absorption and transmission of the film prepared from both the synthesized and the commercially available TiO2 were measured by the UV-Visible Spec-trophotometer. A sharp absorption edge of the TiO2 film was observed. The estimated energy band gap for the film of the commercially available sample was larger than that of the synthesized one
