دراسة تأثير جرعة أشعة جاما على الخصائص الضوئية لأفلام رقيقة من أكسيد الايريديوم محضرة بتقنية المحلول الجيلاتيني

Abstract

Thin films of Ir2O3 have been prepared using Sol-Gel technique with dip coating method, and the effect of gamma dose on the optical properties of Ir2O3 films was studied. The study showed that the gamma dose less than 20 Gy does not affect the optical properties of Ir2O3 films, whereas gamma dose more than 30 Gy strongly affect the optical properties and Band gap of the films. The band gap was increased with increasing the gamma dose more than 30 Gy.
