Structural and Morphological Properties of Fe2O3 and TiO2:Fe2O3 Thin Films Prepared by Spray Pyrolysis Technique

Abstract

Various doping percentage (1, 3 and 5 %) of titanium dioxide TiO 2 were successfully introduced into the iron oxide Fe 2 O 3 thin films obtained by spray pyrolysis technique (SPT) on a glass substrates. The effect of TiO 2 doping on structural and morphological properties of deposited thin films was studied by X-ray diffraction analysis and atomic forces microscope (AFM) respectively. XRD result showed that all samples are polycrystalline and the crystallite size decrease with increasing percentage of (TiO 2 ). All films have peaks appears at (110), (211), (101), (222), (210), (202), (312), (332), (310) and (432) planes with preferred orientation along (211). The (AFM) results shows that the grain size, roughness rate and the root mean square decreases with increasing dopant ratios .
