The disclosure relates to a scintillator and a radiation detector including the scintillator. The scintillator includes a scintillator material. In an embodiment, the scintillator material can include a metal halide doped with Euand co-doped with Sm. The metal halide can include at least one halogen selected from Br, Cl, and I. In an embodiment, the metal halide can include at least one element selected from alkaline-earth metals, rare-earth elements, Al, Ga, and the alkali metals selected from Li, Na, Rb, Cs. In a particular embodiment, co-doping with Smcan shift the scintillation light emission peak to a region of the emission spectrum having a low self-absorbance of the scintillator material.

Scintillator including a material doped with an activator and co-dopant and radiation detector including the scintillator

The disclosure relates to a scintillator material for a radiation detector. In an embodiment, the scintillator material can include a crystalline alkaline-earth metal halide comprising at least one alkaline-earth metal selected from Mg, Ca, Sr, Ba, said alkaline-earth metal halide being doped with at least one dopant that activates the scintillation thereof other than Sm, and co-doped with Sm, said alkaline-earth metal halide comprising at least one halogen selected from Br, Cl, I.
