Abstract

L'invention concerne un matériau scintillateur comprenant un halogénure d'alcalino-terreux cristallin comprenant au moins un alcalino-terreux choisi parmi Mg, Ca, Sr, Ba, ledit halogénure d'alcalino-terreux étant dopé par au moins un dopant activateur de sa scintillation distinct de Sm2+, et co-dopé par Sm2+. Le codopage par Sm déplace le pic d'émission de lumière de scintillation vers un domaine de faible auto-absorbance du matériau.The invention relates to a scintillator material comprising a crystalline alkaline earth halide comprising at least one alkaline earth metal selected from Mg, Ca, Sr, Ba, said alkaline earth halide being doped with at least one dopant activating its scintillation distinct from Sm2 +, and co-doped with Sm2 +. Sm codoping shifts the peak of scintillation light emission to a domain of low self-absorbance of the material.
