Scintillator materials combined with photo detectors are widely used to detect high energy photons and particles. Oxide scintillation materials based on garnet structure like Ce-doped Lu₃Al₅O₁₂ (Ce:LuAG) are promising candidates for scintillator applications because of well mastered technology developed for laser hosts and other applications and easy doping by rare-earth elements. In this report, Mg co-doping effects on scintillation properties of Ce:(Lu,Gd)₃(Ga,Al)₅O₁₂ (LGGAG) were investigated.
