Properties and peculiar features of application of isoelectronically doped A2B6 compound based scintillators

Among 26 compounds, zinc selenide and zinc sulfide crystals are, due to their physico-chemical properties, the best optimized matrices for creation of luminescent materials with output parameters characterizing them as efficient scintillators (highlight output, fast response, high radiation stability, etc.). The first successful experience in this direction was the development of scintillator ZnSe (Te), which has been already shown to be one of the most suitable materials for low-energy X-ray introscopy. With the aim of expanding the application fields of ZnSe and ZnS-based scintillators, we have studied the detect formation processes and luminescent properties if zinc selenide and zinc sulfide crystals doped with anionic (Zn, Cd, Hg) and cationic (O, S, Te) isoelectron dopants (IED). Data are presented on the effect of oxygen, cadmium, tellurium and sulphur upon spectral-kinetic luminescence characteristics of A2B6 compound based scintillator crystals
