Gamma radiation effect on some structural and optical properties of CZO thin films

Abstract

thin films of cobalt doped ZnO were deposited on a glass substrate using chemical spray pyrolysis technique. Absorbance and transmittance spectra were recorded in the wavelength range (300-900) nm before and after irradiation. XRD reveals that the as deposited thin film were hexagonal polycrystalline. The optical parameters such as, optical energy gap , reflectivity ,extinction coefficient and refractive index were determined before and after irradiated by gamma ray. It has been found that all the studied parameters were influnced by radiation.
