Abstract
In this research , the effect of absorbed doses to Gamma rays on some optical Properties for Cadimum Sulfide thin Film (CdS), that prepaired by chemical spry pyrolysis, was studied. This film was exposed to Cs137Source with energy( 662)Kev and activity (370)KBq and radiation absorbed dose (2, 4, 8, 16, 50, 250, 500) Gy and dose rate (222)Gy/min . The results shows that Gamma-rays have effects on (energy gap, absorption coefficient, reflectivity and extinction coefficient).The value was 2.4 eV before radiation and was decreased to (2.38, 2.36, 2.32, 2.32, 2.29 and 2.18)eV after radiation and exposed the film to different doses (2, 4, 8, 16, 50, 250 and 500) Gy respectively. Also the expose of CdS films to radiation doses lead to change curve behavior of curves of optical constants (absorption coefficient, reflectance and extinction coefficient) by increasing of these doses.
