دراسة تاثير التشعيع علي الخواص البصرية لاغشية ZnO المحضرة بطريقة الاكسدة الحرارية السريعة

Thin films of ZnO were prepared by using Rapid Thermal Oxidation System on glass substrate. The films were exposed to a low dose of - rays. The optical properties of thin films are studied before and after irradiation in the fundamental absorption region from their absorption and transmission data. The energy gap of direct allowed are measured also the absorption coefficient, the extinction coefficient, the index of refraction and dielectric constant an its two parts were calculated.
