Photoelectric Characteristics of Nano TiO2 Film Prepared By Spraying Pyrolysis Method

The nanocrystalline TiO2 (nc TiO2) film was prepared by spraying pyrolysis method. Starting material for the synthesis was TiCl4. Phase compositions and crystalline sizes were examined by pattern of XRD, and surface morphology of the thin film was analyzed by SEM and AFM. Optical characteristics were examined by UV – Vis and luminescent spectra (PL). Electric characteristics were examined by measuring resistance changing of films versus temperature. The experimental data showed that the forming films had nanostructure and typical photoelectric characteristics of nano TiO2 material which is similar to the ones prepared by other preparing methods. IF compared to others, this preparing method has such as simple equipments,
inexpensive and available materials; so it is suitable for mass production.
