Abstract
LiYSiO4:Ce is a promising scintillator and some of its properties have been reported in previous papers. In this paper, samples doped with different concentrations of Ce are prepared and studied. First, the relative light yields of the samples are measured as 28.1%–37.1% compared with a standard anthracene crystal being irradiated by α particles and as ∼27.2% compared with NaI being irradiated by X-rays. Second, the effects of sample thicknesses on light yields are presented. Finally the timing behaviors of samples with different doped concentrations being irradiated with alpha particles and X-rays are discussed. The result shows that LiYSiO4:Ce is a kind of fast scintillator (∼ 30 ns) with a moderate light yield that can be used for neutron detection.
