Influence of gamma radiation on optical properties of CdS thin films prepared by chemical bath technique


We have studied the effect of gamma irradiation on the absorption spectra and the optical energy gap of CdS thin films deposited by chemical bath technique method on glass substrate. Transmittance spectra have been recorded in order to determine reflectivity, absorption coefficient , kind of transition .The optical constants such as refractive index , extinction coefficient , real and imaginary part of dielectric constant have also been studied , it was seen that all the parameters under investigation affected by gamma irradiation.
