Effect of gamma ray on optical characteristics of (PMMA/PS) polymer blends

Abstract

Gamma ray effect has been worked out on PMMA/PS blends at different concentrations. The optical constants such as the absorption coefficient, refractive index are calculated, and optical energy gap (direct/indirect) has been studied before and after irradiation. Transmittance, absorbance, and reflectance spectra of pure and blends polymers are investigated.
