Effect of Ca content on optical, scintillation and thermoluminescence performance of LuAG:Ce ceramic scintillators
Original language description
Ce doped Lu3Al5O12 (LuAG:Ce) is a scintillator that attracts attention due to its high light yield, fast scintillation response, and excellent radiation resistance. In this study, optical and scintillation performance of Ca2+ co-doped LuAG:Ce ceramics, fabricated by two-step sintering combined with air annealing, was investigated. In addition, thermoluminescence (TSL) of these LuAG:Ce,Ca ceramics was studied. Decrease of TSL glow curve intensity was observed with increasing Ca2+ content. In particular, the TSL signal becomes hard to detect when Ca2+ content is higher than 0.1 at.%. Ca2+ co-doping is also beneficial for suppressing the slow scintillation component. Sample with Ca2+ co-doping level of 0.1 at.% shows an optimized light yield of 11 700 ph/MeV with scintillation decay showing a high fast component/total intensity ratio of 98.3 %, which is the highest value ever reported in the Ca2+ co-doped LuAG:Ce.
