Abstract

High scintillation efficiency of Eu-doped LiSrAlF₆ (LiSAF) and LiCaAlF₆ (LiCAF) codoped with alkali metal ions has been reported in our recent studies. Thus in this paper, we demonstrated the scintillation properties of 1% Ce-doped LiSAF crystals with 1% alkali metal ions co-doping to increase the light yield and understand the scintillation mechanism. The crystals showed intense emission band corresponding to the 5d-4f transition of Ce³⁺, and their light yields under thermal neutron excitation were higher than that of the Ce only doped crystal. Especially, the light yield of Ce-Na co-doped crystal exceeded about two times that of Ce only doped one.
