ABSTRACT

Titanium dioxide Thin film were formed over well cleaned glass substrate. by home made spin coating technique. For structural analysis XRD spectrum were taken at 300 and annealed temperature 400°C. The thicknesses of the titanium dioxide thin film were measured by using gravimetric technique. FTIR spectrum confirmed the position of titanium and oxygen TiO2 thin film. UV and Absorbance spectrum used for calculating the band gap energy Eg of the titanium dioxide thin film. SEM photograph of the annealed TiO2 thin film were taken for surface analysis.
