| description | •Commercial LYSO:Ce,Ca and YSO:Ce single crystals are compared.•Ca2+ codoping in LYSO:Ce,Ca converts a part of the Ce3+ centers into Ce4+.•Ce4+ center is not harmful for scintillation efficiency in LYSO:Ce,Ca.•YSO:Ce scintillation response is deteriorated by slower host–Ce energy transfer.
The absorption, luminescence and scintillation characteristics of Y2SiO5:Ce (YSO:Ce) scintillator were investigated and compared to those of Lu1.95Y0.05SiO5:Ce,Ca (LYSO:Ce,Ca) scintillator. Due to the Ca2+ co-doping in LYSO:Ce quantified by GDMS analysis, the Ce4+ center is evidenced in the absorption spectra. For 662keV γ-rays (137Cs source), YSO:Ce shows a light yield of 15,300ph/MeV, which is much lower than that of 32,000ph/MeV obtained for LYSO:Ce,Ca. The coincidence timing resolution for 511keV annihilation quanta of 234 and 478ps was obtained, respectively, for LYSO:Ce,Ca and YSO:Ce detectors in coincidence experiment using a BaF2-based detector. Time resolution was also discussed in terms of a number of photoelectrons and decay time of the scintillation pulse. |
