| dc.description.abstract | We have studied the effect of gamma radiation on the absorption spectra of Poly methyl methacylatc doped Blue methyl (PMMA:Blue methyl) films deposited for thickness (25 ± 1 µm) by using solvent casting method. Transmittance and Absorptance spectra have been recorded in order to determine reflectivity. These films show that the energy band gap has decreased from about (2.16eV) before irradation to about (1.97 eV) and (1.21 eV) after irradiation . The optical constants such as refractive index , extinction coefficient , real and imaginary parts of dielectric constant have also been studied , It was seen that all the parameters under investigation were affected by gamma irradiation. | en_US |
