Preparation of titania thin films using Sol-Gel techniques

Abstract

Sol-gel technique have been used to prepare the anastane titania thin films and it is deposited on glass substrates. Under vigorous stirring, substrates are dipped into the solution. The films were dried at atmospheric temperature. Oley amine (OM) was used as a chemical agent within the synthesis part and it had been aggressively stirred with titanium tetraisopropoxide (TTIP). Samples of thin films are annealed under 550°C for 15 hours. To study the properties of structure, X-Ray diffraction (XRD) analysis and Raman Spectroscopy has been taken place. Also by using Ultraviolet (UV) Spectroscopy, optical properties are analyzed for the samples. XRD results illustrated the amorphous structure and section of TiO2 and these results were additional confirmed by Raman spectrum analysis. Then ultraviolet light spectrographic analysis has been used for preparation of TiO2 lean films in association with the energy band three 3.26 and 3.22 eV, it is easy refers to make different in crystal structure for anatase titania. In addition, each samples have high transmission.
