This paper presented the preparation of TiO 2 thin film on empty glass and Indium Tin Oxide (ITO) glass by spin coating 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 TiO 2 were measured by the UV-Visible Spectrophotometer. A sharp absorption edge of the TiO 2 film was observed. The estimated energy band gap for the film of the commercially available sample was larger than that of the synthesized one.
