Czochralski Growth and Scintillation Properties of ${\rm Ce}:({\rm Gd},{\rm Y},{\rm Lu})_3$ $({\rm Al},{\rm Ga})_5{\rm O}_{12}$ Single Crystals

1-inch size Ce1%:Gd 2 Lu 1 Al 2 Ga 3 O 12 , Gd 1 Lu 2 Al 2 Ga 3 O 12 , Gd 1 Y 2 Al 1.5 Ga 3.5 O 12 and Lu 2 Y 1 Al 2 Ga 3 O 12 were grown by the Czhocralski (Cz) method. The EPMA techniques is employed to check their chemical composition. Luminescence and scintillation properties were also evaluated. The Ce1%: Gd 1 Y 2 Al 2 Ga 3 O 12 sample showed the highest light yield of around 40 \thinspace000 photon/MeV. The scintillation decay time was 46.6 ns(63%) and 157 ns(37%).
