Influence of Irradiation on some Optical Properties of (CdO) Thin Films Prepared by Spray Pyrolysis

Full Text PDF

Abstract:

In this research, the irradiation influence on optical properties of Cadmium oxide thin films deposited on glass substrate via spray pyrolysis method were studied. The thickness of the prepared thin films were 400 and 500 nm respectively. The flow rate was 10 ml/min and the substrate temperature was held constant at 450°C. The thin films are irradiated with gamma ray from Cs-137 of energy 0.662 MeV, the irradiation time is two weeks. The optical absorption and transmission was studied by using UV-Visible spectrophotometer. The absorption coefficients increase after irradiation, while the optical band gaps for 400 nm (CdO) decrease after irradiation from 2.32 to 2.27 eV and for 500 nm (CdO) from 2.30 to 2.12 eV.
