Abstract

The effect of gamma and electron irradiation on optical and IR absorption, as well as on photoluminescence of samples with a PS polystyrene base and pTP and POPOP additives, has been studied. A decrease in the luminescence intensity of irradiated samples in the ranges of 300–380 nm and 380–500 nm was found, which correlates with changes in the IR absorption spectra of the samples, which is due to the degradation of the structure of the aromatic benzene ring in the matrix of the polymer base and the destruction of additives.
