Photoreactive titanium oxide layer prepared from a titanium naphthenate
Highly transparent titanium oxide thin films were prepared on soda-lime-silica slide glass substrates from a titanium naphthenate precursor. Films prefired at 500 degrees C for 10 min were finally heat treated at 500 degrees C for 30 min in air. Crystallinity of the films was analyzed by high resolution X-ray diffraction analysis. A sharp absorption edge of the TiO2 film was observed. The estimated energy band gap for the film is larger than that of single crystal TiO2. (c) 2006 Elsevier B.V. All rights reserved.
