硅酸铋闪烁晶体及其掺杂改性
Development of Bismuth Silicate Scintillation Crystals and Doping Effects
摘要
Abstract
Bismuth silicate (i.e., Bi4Si3O12, BSO) single crystal is an excellent oxide scintillation material with the eulytite structure. It shows a decay time (100ns) faster than that of BGO crystal and its light yield is greater than that of PWO crystal, thus it is regarded as one of the promising candidates for dual readout calorimeters. This review represented recent development of the phase diagram, growth, scintillation properties and doping effects of BSO crystal. The advantages and disadvantages of different growth techniques were discussed. The influence of dopant on the scintillation properties and crystallization behavior was summarized. The improvement of scintillation properties by doping Dy3+ ions is attributed to the compensation of Bi3+ vacancy by a small amount of Dy3+ ions. In addition, Re-doped BSO crystals show some potential applications as phosphors and laser materials.关键词
