Radiation effect on the optical and structural properties of CdTe : Zn thin films

الملخص EN

The Films of Cd Te : Zn were prepared on a glass by using vacuum vapor deposition technique.

The x-ray diffraction pattern revealed that the films have polycrystalline with FCC structure and the preferred orientation was along (111) plane.

The films were exposed to a low dose of gamma ray.

(5μCi for 30 days).

Transmission and absorptance spectra were recorded in the range of (400-1100) nm before and after irradiation.

It was found that irradiation has a clear effect on the optical and structural properties which include the transmit ion and absorption spectra, extinction coefficient, refractive index, and the energy gap.
