تاثير التشعشع علي بعض الثوابت البصرية لاغشية اوكسيد الكادميوم المشوبة بالانتمون

Thin films of CdO:Sb were prepared on glass substrates using spray pyrolysis technique. The films were exposed to a low dose of Y- rays. Transmission and absorptanace spectra were recoded before and after irradiation, it was found that irradiation affected the optical constants, which include, extinction coefficient, refractive index, real and imaginary part of dielectric constant and optical conductivity.
