%X Cerium doped yttrium pyrosilicate Y2Si2O7:Ce(YPS) single crystal was obtained through the floating zone method. The scintillation and thermoluminescence (TL) properties of YPS:Ce were studied. The scintillation and optical properties of YPS:Ce crystal were characterized by light output, decay time and transmittance. Its potential application prospect as scintillation material was also evaluated. It was noticed that the decay time of YPS:Ce was about 30.16 ns, which was the fastest value in the cerium doped silicate scintillators. The traps in YPS:Ce were studied through TL spectrum. Three traps were detected in the temperature range of 300-500 K, corresponding to three trap in YPS:Ce sample. The physical parameters of these traps (including energy level, frequency factor) were determined through fitting the 2D (temperature-luminescence intensity) TL curve. Combined with 3D (temperature- wavelength-luminescence intensity) TL spectra, the TL mode of YPS:Ce sample was proposed.
