AbstractGadolinium iodide doped with Cerium (GdI3:2%Ce) and undoped gadolinium iodide (GdI3) crystals were grown by vertical Bridgman method with sealed quartz crucible. Crystal ingots with dimension of φ15 mm×20 mm were cut and polished to be plates of 12 mm×10 mm×2.5 mm and 11 mm×8 mm×2.5 mm. GdI3:2%Ce without crack and inclusion were encapsulated for all the measurements. X-ray diffraction analysis shows that the Ce3+-doped GdI3and undoped GdI3crystal have the same structure. X-ray and ultraviolet excited luminescence spectra of GdI3:2%Ce present broad emission bands peaking at 520 nm and 550 nm, respectively, which correspond to 5d-4f transition luminescence of Ce3+. Three peaks located at 262, 335 and 440 nm can be observed in excitation spectra when photoluminescence is monitored at 550 nm. The GdI3:2%Ce crystal presents an excellent energy resolution of 3.4% and decay time of (58±3) ns under excitation of 662 keV gamma-rays from137Cs source. The results show the GdI3:2%Ce crystal is a promising scintillator for gamma ray and neutron detection. © 2017, Science Press. All right reserved.
