Influence of Gamma Radiation on Structural and Optical Properties of Fe2O3 Thin Films Prepared by Chemical Spray Technique

Full Text PDF

Abstract:

The purpose of this research is studying the effect of gamma radiation on the structural and optical properties of iron oxide Fe2O3 thin films. The technique used for prepared the thin films was thermal chemical spray. The effect of Co60 irradiation on the structural and optical properties of the thin films was investigated. The crystal structure were studied by XRD pattern. The surface tested from crack and defect was looke by used microscope image. The absorption and transmission spectra by used UV/VIS for the as deposited and irradiated thin films. The energy gap and absorption coefficient were studied. It's found that the energy gap for the un-irradiated sample was 2.3 eV and than after exposed to gamma radiation at (25,50,75,100 and 125) Gy the energy gap decreased and above 5o Gy was increasing. The absorption coefficient increased until (12x104) cm-1 at 50 Gy and than was decreasing to (2x104) cm-1 at 125 Gy. The effect of radiation on the structural and optical properties was positive at the levels of irradiation used.
