Title: Evolution of structural and optical properties of photocatalytic Fe doped TiO{sub 2} thin films prepared by RF magnetron sputtering

Undoped and Fe doped TiO{sub 2} thin films have been prepared by RF magnetron sputtering. Pure TiO{sub 2} thin film exhibited an amorphous-like nature. With increase in iron concentration (0–0.1 at%), the films exhibited better crystallization to anatase phase . Red shift of absorption edge was observed in the UV-vis transmittance spectra . At higher Fe concentration (0.5 at%), onset of phase transformation to rutile is noticed. Photocatalytic properties of pure and 0.1 at% Fe doped TiO{sub 2} thin films were investigated by degradation of methylene blue in UV light, visible light and light from Hg vapor lamp. 70% degradation of methylene blue was observed in the presence of Fe doped film in comparison with 3% degradation in presence of pure TiO{sub 2} film when irradiated using visible light for 2 h.
