Gamma ray detection properties of lutetium aluminate scintillators

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 /spl gamma/-rays has been accomplished using LuAP coupled to semiconductor photosensor...

Zusammenfassung: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 /spl 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.
