Abstract

Titanium dioxide is currently the focus of intensive research because of their interesting chemical, electrical and optical properties. In this work, TiO2 thin films were prepared by sol gel method, and have been deposited by spin coating technique onto glass substrates (3 - TiO2/glass). In this work, we report the effect of the spin speed (2900, 3200 and 4900 rpm) on different optical properties of the films. The samples were characterized by means of Raman spectroscopy, hall measurement and UV-Visible spectrophotometer. The transmission spectra of titanium dioxide thin films indicate that there are two parts, the first is transparent in the visible wavelength spectrum region and the second is opaque in the UV ranges. We found that the transmission curves and the calculated optical band gap increase when thespin speed increases. The Raman spectra have shown the Anatase phase.
