Influence of Irradiation on Electronic Transition of (CuO) Films Prepared by Chemical Spray Paralysis Technique

Abstract

In this research, We study the effect of irradiation by gamma rays from (Cs137) source for the period time (21) days on optical propertices such as absorption coeffeicient ()and energy gap (Eg) for copper oxides thin films (CuO) prepared by the chemical spray pyrolysis and deposited on glass substrates at (350oC) for two different thicknesses ( 1000Åand 3000Å) .
