Abstract
LuAP and LuYAP are promising single-crystal scintillators for use in the next generation of positron emission tomographs. The practical crystal composition in terms of major components and Ce-doping level is however under discussion yet. Bridgman and Czochralski melt techniques are used to develop various crystal compositions for scintillation studies and final composition choice. In this paper we compare performance of 30 LuAP, LuYAP and YAP variously Ce-doped single-crystals grown by Bridgman technique, which reflect potential of existing materials and technologies. In addition to available optical properties, the chemical composition of solid solutions is described in terms of variation of Ce concentration and of Lu/Y ratio.
