Abstract

Cerium doped lutetium pyrosilicate Lu₂Si₂O₇ (Ce: LPS) scintillator presents high light output (average value: 26,300 ph/MeV), a relatively good energy resolution (10%) and a fast decay time (38 ns) without afterglow. The luminescence efficiency remains very high when the temperature increases up to 450 K. It makes this new scintillator very attractive. We compare its properties to those of another recently developed cerium doped silicate, Ce: Lu_2(1-x)Y_2xSiO₅ (LYSO).
