Journal of Theoretical and Applied Physics (JTAP) Effect of gamma ray on optical characteristics of (PMMA/PS) polymer blends Volume 11 (2017) Issue 3, September and October 2017 2023 11 17 Effect of gamma ray on optical characteristics of (PMMA/PS) polymer blends 10.1007/s40094-017-0259-7 EN Journal Article 2023 11 17 AbstractGamma 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.
