Abstract

L'invention concerne un matériau scintillateur comprenant un halogénure de cation cristallin dopé par Eu2+ et co-dopé par Sm2+. Le co-dopage par Sm déplace le pic d'émission de lumière de scintillation vers un domaine de faible auto-absorbance du matériauThe invention relates to a scintillator material comprising a crystalline cation halide doped with Eu2 + and co-doped with Sm2 +. Sm co-doping shifts the scintillation light emission peak to a low self-absorbance domain of the material
