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

Asia Hussein Kadhim, Nahida B. Hasan


Various doping percentage (1, 3 and 5 %) of titanium dioxide TiO2 were successfully introduced into the iron oxide Fe2O3 thin films obtained by spray pyrolysis technique (SPT) on a glass substrate. The effect of TiO2 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 decreases with the increasing percentage of (TiO2). 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 show that the grain size, roughness rate, and the root mean square decreases with increasing dopant ratios.
