The spectra and kinetics of fast and delayed radiation were also studied, and the obtained results were interpreted. It is shown that exciton processes play a major role in the electronic processes observed in the studied samples. In particular, it is shown that the phosphorescence of stilbene and para-terphenyl granules mainly becomes impurity in nature with increasing granules of these substances. The kinetics of attenuation of delayed radiation of granular samples of stilbene and para-terphenyl was studied. The presence of delayed radiation observed in the region of rapid fluorescence is shown. This effect is associated with the annihilation of triplet excitons. The obtained results can be used by developers of ionizing radiation registration systems.  Product Description popup.authors popup.nrat_date 2021-12-20 Close
