Author(s): Influence of Gamma Radiation on Optical Properties and the surface, volume energy loss function of (PHHP) films

Thin films of (PHHP) were investigated for gamma – irradiation samples were fabricated using cast method. Thin films of (PHHP) were exposed to Cs-137 gamma – irradiation source at a dose rate 0.5 Gy/min at room temperature. Absorption spectra for(PHHP) films were recorder and values of the optical properties ( energy gap, interband transition ((real and imaginary)) strength and surface energy loss function SELF and volume energy loss function VELF and optical constant ( n, k ))for no irradiation and gamma- irradiated samples were calculated. It was found that the optical absorption spectral distribution is sensitive to the radiation influence at the wave length 350 nm
