Scintillation response of Lu3Al5O12:Pr3+ single crystal scintillators

Popis výsledku v původním jazyce

We present the scintillation responses of Pr3+-doped Lu3Al5O12 single crystals grown by the Czochralski method with different Pr3+ concentration of 0.19, 0.31, and 0.43 mol% in the crystal. The light yield and energy resolution were measured using photomultiplier tube (XP5200B PMT) readout. High light yield of 15,900 photons per MeV and an energy resolution of 6.5% for 662 keV c-rays (137Cs source) were obtained with the LuAG:Pr (0.19%) crystal. The variation of light yield and energy resolution with praseodymium concentration was also observed. The light yield non-proportionality and energy resolution versus c-ray energy were measured and the intrinsic resolution was calculated after correcting the measured energy resolution for PMT statistics. Very good proportionality of the light yield was found within 5% over the energy range from 1274.5 keV down to 32 keV.
