Abstract

Sc doped YyLu3-yAl 5O12 (y = 0-1) single crystals were grown by the μ-PD method. EPMA techniques were employed to check their chemical composition. Luminescence characteristics were measured. Anti-site defect-related host emission was observed within 280-360 nm wavelength. The light yield was increasing with Y concentration and with an optimum for Sc2% concentration. The Sc 2% doped Y3Al5O12 showed the highest light yield value around 30,000 photon/MeV and 670 ns scintillation decay time using a photomultiplier detector (R7600U). Substitution effects of the Lu site and their influence on luminescence and scintillation properties were studied.
