| 英文摘要 | A comprehensive study of the optical, radioluminescence and scintillation properties of both the Lu3+ rich and Lu3+ deficient non-stoichiometric Lu(3+x)AG:Ce,Mg (Lu3+xAl5O12:Ce,Mg, x =-4,-1, +1 and +4 at.%) ceramics are performed, completed further by the microstructure and defects characterization. Small deviation from the stoichiometric composition as well as Mg2+ codoping plays a crucial role in ceramic transparency, radioluminescence intensity and the timing characteristics of scintillation response. The Lu-AI antisite defects could be suppressed efficiently by controlling Lu3+ content below stoichiometry of LuAG host. MgO (Mg2+ ions) as effective sintering aids, can improve both the optical quality and scintillation performance (light yield, scintillation decay times and the ratio of fast decay components). We generally discuss the composition dependence of defects and properties tailoring. We also performed the systematic comparative study with the stoichiometric LuAG:Ce,Mg ceramic and the commercial EGO and LuAG:Ce single crystals. (C) 2016 Elsevier Ltd. All rights reserved. |
