摘要: Abstract The optical and scintillation properties of LaCl3 : 0.57% Ce, LuBr3 : 0.021%, 0.46%, 0.76% Ce LuCl3 : 0.45% are studied under optical, X- γ-ray excitation. highest light yield 40000±4000 photons per MeV (ph/MeV) absorbed energy was measured for Ce. An resolution (FWHM over peak position) of, respectively, 7.0±0.5%, 6.0±0.1%, 7.8±0.3%, 6.5±0.5% 18.0±0.5% observed the 662 keV full absorption peak. decay curves can be described with three components: 20±2, 330±30 ns 2.2±0.2 μs LaCl3 : 0.57%; 32±3, 450–550 ns >5 μs LuBr3 : 0.76%; 50±5, 250–350 ns >4 μs LuCl3 : 0.45%.
