摘要：

Cerium-doped lutetium orthosilicate (Ce:Lu2SiO5, LSO) scintillation ceramics were fabricated by using spark plasma sintering (SPS) technique starting from synthesized submicron polycrystalline LSO luminescent powder. Polycrystalline translucent LSO ceramics were rapidly densified under optimized sintering conditions of 1350 degrees C/5min. The relative density of obtained translucent LSO ceramic reached 99.5% theoretically. Under excitation of 360nm, a broad emission peak was detected in the wavelength range of 380nm to 600nm. The relative emission intensity of obtained LSO ceramic attained 75% of LSO single crystal scintillator. The luminescent decay time was measured to be only 9.67ns. The good luminescent characteristics make LSO polycrystalline ceramic a promising scintillator candidate for radiation detection in future.
