A ceramic lithium indium diselenide or like radiation detector device formed as a pressed material that exhibits scintillation properties substantially identical to a corresponding single crystal growth radiation detector device, exhibiting the intrinsic property of the chemical compound, with an acceptable decrease in light output, but at a markedly lower cost due to the time savings associated with pressing versus single crystal growth.

Embodiments of the invention provide a scintillator material, a scintillator system, and/or a method of detecting incident radiation using a scintillator material, or scintillator system, comprising a polymer material that comprises chromophores. Additional embodiments provide a scintillator material, scintillator system, and/or a method of detecting incident radiation using a sctintillator material, or scintillator system, comprising a polymer material having one, two, three, or more, organic dyes dissolved therein wherein the polymer material having the one, two, three, or more dyes dissolved therein comprises chromophores. At least one of the dyes, termed the base dye, has a concentration in the range 0.5 to 3.5 mol/L. In a specific embodiment, the base dye has a concentration in the range 1.0 to 3.0 mol/L. This base dye concentration is high enough to achieve a substantial triplet-triplet state annihilation rate despite the negligible diffusion of the dye in the rigid polymer matrix.
