Abstract

Scintillation properties of Ce doped Cs₂LiYBr₆, Rb₂LiScBr₆, Rb₂LiYBr₆, Rb₂LiLaBr₆, Rb₂LiYI₆ elpasolite, and Li₃YBr₆ monoclinic inorganic thermal-neutron scintillator crystals were investigated. Light yields and decay times were studied. Cs₂LiYBr₆:Ce and Rb₂LiYBr₆:Ce show a high light yield of ≥64,000 photons per thermal neutron. More details will be presented and advantages and disadvantages of these new scintillator materials will be discussed.
