A new scintillator material, lutetium orthoaluminate (LuAlO{sub 3}:Ce or LuAP), has been characterized by measuring its light output, scintillation decay time and energy resolution. Successful detection of 511 keV {gamma}-rays has been accomplished using LuAP coupled to semiconductor photosensors (silicon avalanche photodiode and silicon p-i-n photodiode). The background spectrum due to the radioactive isotope {sup 176}Lu in LuAP has been measured and characterized, and potential applications of LuAP are addressed.
