Abstract

Cerium-doped gadolinium pyrosilicate single crystals Ce : Gd₂Si₂O₇ with various Ce concentrations of 2.5-25 mol% were fabricated using floating zone method. Their scintillation performances were investigated under irradiation of gamma rays of ¹³⁷Cs. The Ce concentration dependence of scintillation characteristics and high- performance scintillation characteristics were obtained: 3-5 times greater light output than BGO single crystals, rapid decay, and good energy resolutions of 5.1-8.4%. X-ray diffraction patterns of Ce : Gd₂Si₂O₇ also showed Ce concentration dependence of the crystal structure of Ce : Gd₂Si₂O₇.
