Y2SiO5:Ce (YSO:Ce) or Cerium doped Silicate Yttrinm is a bright and fast light scintillator with the emission peaked at 420 nm, easy to match with PMT and SiPM. it has similar decay time with LYSO(Ce) (50-70ns), but no background(Lutecium). Mechanical processing of YSO:Ce scintillators is easier compared to other silicates. 
YSO(Ce) is often made into pixellated array and multi-layer arrays for nuclear medicine PET applications.
