  • Patent number: 11326100
    Abstract: 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 Eu2+ and co-doped with Sm2+. 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 Sm2+ can shift the scintillation light emission peak to a region of the emission spectrum having a low self-absorbance of the scintillator material.
