Abstract
The properties of organic polycrystalline scintillators produced by different methods are studied. It is shown that polycrystals in the shape of plates, made by compacting powders of solution-grown organic crystals at premelting temperatures, exhibit better characteristics. Their energy resolution for α and β particles is higher by 40% and, for X-rays, by 20–25% than the resolution of polycrystals produced by other methods. The scintillation properties of such polycrystals are comparable to the characteristics of organic single crystals. [ABSTRACT FROM AUTHOR]
