| Abstract | ||
| In this research, the effect of γ -rays from (Cs137) source a time period (21) days on optical properties such as energy gap (Eg) , the optical Transmittance (T%) spectra , optical Absorption spectra (A), optical reflectance spectra (R %), absorption coefficient () ,Urbach energy (Eu), extinction coefficient (k) , refractive index(n) and dielectric constants for the lead selenide (PbSe) thin films prepared by the thermal evaporation on a glass substrate in 5 ×10-5 mbar pressure at room temperature of thickness (7000 Å) and rate of deposition (1.46 nm/s ) . it were seen that all the parameters under investigation affected by gamma irradiation. | ||
