Optical Behaviour of Transparent Thin Films of Sr-Doped TiO₂ for Optoelectronic Devices

Abstract:

Transparent thin films of 3% Sr – doped TiO₂ were prepared by spin coating technique on a glass substrate and annealed at different temperatures. The optical properties of the films were studied using UV – Visible spectroscopy and Photoluminescence ( PL ) spectroscopy. The optical band gap is found to change with the annealing temperature of the deposited films. The PL emission spectra showed a sharp intense peak near the violet region. AFM analysis was used to study the surface topography of the films. The study shows potential applications of the prepared films in optoelectronic devices.
