Abstract

Short overview of scintillating properties of multicomponent (Lu, Y, Gd)₃(Ga, Al)₅O₁₂ garnets and a comparison with properties of Ce3⁺- and Pr³ ⁺- doped single or mixed rare earth aluminum garnets RE₃Al₅O₁₂ where RE are Y, Lu or their mixture in asked ratio, will be presented. The highest light yield up to 27000 ph/MeV was observed on LuAG:Ce while that observed on LuAG:Pr can reach ∼20000 ph/MeV at 10 μs long shaping time. These values are almost only one half of those of well prepared multicomponent Gd₃Ga₃Al₂O₁₂:Ce crystal with light yield ∼50000 ph/MeV.
