Many Ce-doped (Lu,Y)AlO3 solid solution single crystals of various Lu/Y ratio and dopant concentration have been grown using the vertical Bridgman and Czochralski processes. Light yields of around 200% of EGO have been measured under gamma-ray excitation. The as-grown and gamma-ray-induced color centers have been compared in crystals of various composition. The absorption properties were characterized in as-grown crystals and after exposure to 1 Mrad of Co-60. The extent of radiation-induced optical absorption was found to be dependent on the initial light transmission properties of the crystals.
