Description
Summary:Ce 1% doped Lu sub(2)Gd sub(1)Al sub(2)Ga sub(3)O sub(12) (LGAGG) single crystals with a diameter of 50 mm and length of 150 mm were grown by the Czochralski (Cz) method using an RF heating system. The EPMA techniques is employed to check homogeniousity of chemical composition. Luminescence and scintillation properties were also evaluated. The grown LGAGG showed light yield of around 25,000 photon/MeV and energy resolution was 9.8%62 keV. The scintillation decay time was 53.6 ns at room temperature.
