Effect of $Li^+$ ions co-doping on luminescence, scintillation properties and defects characteristics of LuAG:Ce ceramics / Liu, Shuping (Shanghai Inst. Ceramics) ; Feng, Xiqi (Shanghai Inst. Ceramics) ; Mares, Jiri A (Prague, Inst. Phys.) ; Babin, Vladimir (Prague, Inst. Phys.) ; Hu, Chen (Shanghai Inst. Ceramics) ; Kou, Huamin (Shanghai Inst. Ceramics) ; D'Ambrosio, Carmelo (CERN) ; Li, Jiang (Shanghai Inst. Ceramics) ; Pan, Yubai (Shanghai Normal U.) ; Nikl, Martin (Prague, Inst. Phys.)
Monovalent $Li^+$ codoped $Lu_3Al_5O_{12}$:Ce (LuAG:Ce) optical ceramics were fabricated by solid state reaction method and further optimized by an air-annealing process. Optical absorption, radioluminescence spectra and scintillation properties such as light yield, scintillation decay times and afterglow were measured and compared with those of the $Li^+$ free LuAG:Ce ceramic and the commercial LuAG:Ce single crystal samples.

Optical, luminescence and scintillation characteristics of non-stoichiometric LuAG:Ce ceramics / Liu, Shuping (Shanghai Inst. Ceramics ; Beijing, GUCAS) ; Feng, Xiqi (Shanghai Inst. Ceramics) ; Mares, Jiri A (ASCR, Prague) ; Babin, V (ASCR, Prague) ; Nikl, Martin (ASCR, Prague) ; Beitlerova, Alena (ASCR, Prague) ; Shi, Yun (Shanghai Inst. Ceramics) ; Zeng, Yanping (Shanghai Inst. Ceramics) ; Pan, Yubai (Shanghai Inst. Ceramics) ; D’Ambrosio, Carmelo (CERN) et al.
Non-stoichiometric $Lu_{3+x}Al_{5}O_{12}:Ce$ ($Lu_{3+x}$AG:Ce, x=1, 2, 3 and 4 %) ceramics were fabricated by solid state reaction method and further optimized by an air-annealing process. Absorption, luminescence spectra and scintillation characteristics such as light yield, scintillation decay times, energy resolution, proportionality and afterglow were measured and compared with those of the latest LuAG:Ce single crystal and stoichiometric LuAG:Ce,Mg ceramic samples.

Towards Bright and Fast Lu3Al5O12:Ce,Mg Optical Ceramics Scintillators / Liu, Shuping ; Mares, Jiri A. ; Feng, Xiqi ; Vedda, Anna ; Fasoli, Mauro ; Shi, Yun ; Kou, Huamin ; Beitlerova, Alena ; Wu, Lexiang ; D'Ambrosio, Carmelo (CERN) et al.
The recent advent of Lu 3 Al 5 O 12 :Ce optical ceramics marks a turning point in scintillator material technology. Because of their lower preparation tem-perature, brightness, and robustness such materials can now compete with single crystals. [...]
