摘要：

(Gd-0.75,Ce-0.015,La-0.235)(2)Si2O7 (Ce:La-GPS) single crystals co-doped with 0, 100, 200, 500 and 1000 ppm Zr were grown by the Czochralski process, and their scintillation properties were investigated. We investigated the co-doping effect of a stable tetravalent ion in Ce:La-GPS for the first time. The scintillation decay times in the faster component were shortened with increasing the Zr concentration. While the non-co-doped sample showed similar to 63 ns day time, the Zr 100, 200, 500 and 1000 ppm co-doped samples showed similar to 61, similar to 59, similar to 57, similar to 54 ns, respectively. Additionally, light output, photon nonproportional response (PNR) and other optical properties were investigated. (C) 2016 Elsevier Ltd. All rights reserved.
