Investigating scintillation properties of Ce doped Cs2LiYBr6

A promising composition, Ce doped Cs₂LiYBr₆ (CLYB) originally introduced by van Loef et al. has been investigated recently as a gamma-ray and neutron detector. It belongs to the elpasolite family and has a cubic structure. A single crystal of this material has been grown using the vertical Bridgman method. Scintillation properties such as energy resolution, emission, light yield, non-proportionality, and decay times are discussed in this paper. It can be used effectively to discriminate between the gamma and neutron events using pulse-shape discrimination (PSD) technique.
