Abstract
TiO2 thin films were prepared on glass substrates by sol- gel spin coating method.
Tiatanium tetra iso propoxide, ethanol and diethanolamine were used to prepare the coating solution.
The prepared films were annealed at different temperatures of 350, 450 and 550°C. The structural
properties were investigated by using X-ray diffraction technique and grain size was calculated. The
optical properties were investigated using UV-Vis spectroscopy and PL studies and the optical band
gap was calculated. The TiO2 thin films prepared at 450°C were used as photo catalysts for photo
catalytic degradation of methylene blue dye. A maximum efficiency of 88 % is reported.
