Study of the Irradiation effect on the optical properties for the SnO2 thin film

Abstract

In this report investor the optical properties of the thin film SnO2 , before and after Irradiation by Argon Laser Ar+. We found same varieties has been achieve on optical properties of a thin film SnO2.The Energy Gap had decreased from 2.91ev to 2.88ev, its meaning that the Irradiation had improved the equality of the thin film, in additional we found that the irradiation has been change another optical properties, the Absorption coefficient increased, so the value Extinction coefficient increased, also found increasing in the Reflected index. It refer that the irradiation had optimized all the optical properties on a thin film SnO2.
