| Abstract | ||
| In this research, study effect of radioactive dose for Alpha-practical, by using radioactive source of (Am241),which has energy (5.49)MeV and activity of 76 KBq on optical Properties of Zinc Sulfide (ZnS) thin films prepared by thermal evaporation vacuum, with thickness (300)nm. This research concerned with the study of the optical properties (energy gap, absorption coefficient, reflectance and extinction coefficient). The ZnS thin films were evaluated spetrophoto metrically irradiated with Alpha-practical with doses of values )2,4,10.6,53) Gy. The energy gap was calculated before irradiation (3.5)eV and after irradiation (3.4,3.3,3.2,3.1) eV respectively. Result of study describe that exposure of ZnS thin film radioactive doses lead to decrement value of energy gap and increase of value of others properties with change curve behavior by increase of that doses. | ||
