Structural and optical behaviour of cerium doped TiO2 thin films prepared by spray pyrolysis method

Abstract

The Cerium doped titanium oxide (CexTi1−xO2 with x = 0 and 0.1) thin films were deposited on the glass substrate with the substrate temperature of 400 °C using Spray pyrolysis technique. The phase confirmation of the grown thin films was confirmed by X-ray diffraction analysis. From the XRD analysis, the sample shows the amorphous structure. Their surface morphology was probed using Scanning Electron Microscopy and the quality of the grown films was identified by atomic force microscopy analyses. The functional group and optical studies of the prepared films were characterised by Fourier Transform Infra-Red spectroscopy and UV–Vis-double beam spectrometer. The optical energy gap was determined by transmittance measurement.
