SCINTILLATOR MATERIAL COMPRISING A CRYSTALLINE CATION HALIDE DOPED BY EU²⁺ AND CO-DOPED BY SM²⁺

摘要

The invention concerns a scintillator material for an ionising radiation detector comprising a cation halide comprising at least one distinct cation of Eu²⁺ and of Sm²⁺, doped by Eu²⁺, and co-doped by Sm²⁺, said cation halide comprising at least one halogen chosen among Br, Cl and I, and preferably at least one cation chosen among the alkali earths, the rare earths, Al, Ga and the alkali metals chosen among Li, Na, Rb, Cs. The co-doping by Sm²⁺ moves the scintillation light emission peak to an emission spectrum domain having a low self-absorbance of the material.
