Study of the Optical Properties for (CdS) Radiated by (He-Ne Laser)

Abstract

In the present paper the effect of continous was studied (He-Ne Laser) for (30 minute) that have power bigger than (1 mw) Length wave (680.8) on the (CdS) thin film,was calculated optical properties (Forbidden Energy Gap, Absorption Cofficient, Reflectance),they study revealed that the (Forbidden Energy Gap) decreased, ( Absorption Cofficient) increased, and (Reflectance) showed little decreased.
