Title: Mixed compound organic glass scintillators

Abstract

A mixed compound glass scintillator includes a first compound and a second compound. The first compound has a Tg greater than 25° C., is organic, is capable of generating luminescence in the presence of ionizing radiation. The first compound includes a central species and a luminescent organic group bonded to the central species or to an optional organic linker group. The central species is selected from the group consisting of: carbon, silicon, and tin. The optional organic linker group, if present, is bonded to the central species and the luminescent organic group. The second compound also has a Tg greater than 25° C. The first and second compound are mixed and melted to form a glass material.
