Study The effect of Annealing and Argon Laser Irradiation on the optical properties of SnO2 Thin film

Abstract

In this research we study the effect of Argon Laser Irradiation and annealing on the some optical properties of SnO2 Thin film . These films were prepared by chemical spray pyrolysis method. The film thickness was 1500 A°. optical properties such as (Reflection, Energy band gab, Absorption coefficient, Refractive index, and extinction coefficient) as a function of photon energy have been studied within the wavelength range (300-900) nm, using (u v-visible) Spectrophotometer, before and after irradiation and annealing. it is found that the optical properties were change .
