Electronic processes and radioluminescence for crystalline systems with different structure perfection

The electronic processes causing the radioluminescence of organic molecular scintillators, i.e. single crystals, polycrystals, plastics, liquids, are discussed. Pure and binary systems were investigated. The analysis is based on the review of experimental results of radioluminescence intensity and p ulse shape measurements, both well known and new, and on the modem theory o f radioluminescence process in organic condensed media ([1]). Specific quen ching of the radioluminescence, which appears in the cases of high density of excitation, is analysed for organic solids with different structure perf ection.
