Great Scintillating Properties of a YAlO3:Ce Crystal

We study the decay time constants and light output of an 18×18×1 mm3 YAlO3 crystal doped with cerium. The result shows that the light pulse is composed of fast and slow components. The fast component has a decay time constant of 24.05±0.15 ns with an intensity of 81.57±0.97% and the slow component has a decay time constant of 87.67±2.49 ns with an intensity of 18.51±1.34%. The measured light output is 3608±80 photoelectrons/MeV without the correction for the quantum efficiency of the photomultiplier tube XP2262B.
