摘要
LSO scintillation crystals with improved scintillation and optical properties are achieved by controlled co-doping a LSO crystal melt with amounts of cerium and an additional codopant such as calcium or other divalent cations. Crystal growth atmosphere is optimized by controlling the amount of oxygen in the atmosphere. Zinc is added as an additional material to restabilize crystal growth where calcium co-dopant is added. The decay time of the scintillation crystal can be controlled by controlling the concentration of co-dopant added.
