| Abstract | ||
| The effect of Argon Laser Irradiation on the some optical properties of ZnO Thin film after Annealing have been studied. These films were prepared by chemical spray pyrolysis method. With thickness 3500 A°. Optical properties such as (Energy gap, Absorption coefficient, Refractive index, and extinction coefficient) as a function of photon energy have been studied within the wavelength range (300-900) nm, using (uv-visible) Spectrophotometer, before and after irradiation. It is found that the optical properties were decreased by irradiation , from (3.22eV) to (3.18, 3.11) eV , respectively for (30,60) min . | ||
