【摘要】 以铈离子Ce3+激活的LaBr3晶体(LaBr3:Ce3+)是近年来发现的一种新型无机闪烁体材料,较高的光产额、较好的能量分辨率、较快的衰减时间等优良性质,使其成为NaI(Tl)等传统闪烁体材料有力的竞争者。论文通过重点比较LaBr3:Ce3+晶体与NaI(Tl)晶体的性质,同时列举实例说明它的应用,力求比较全面地反映LaBr3:Ce3+晶体的性质。更多还原

【Abstract】 The cerium doped lanthanum bromide crystal(LaBr3:Ce3+)is a new inorganic scintillator crystal developed recent years.The good characters such as high light yield,high energy resolution,fast decay time,have made it a potent competitor with traditional scintillator crystals such as NaI(Tl).In the article,I will principally compare the characters of LaBr3:Ce3+ crystal to NaI(Tl),and list examples to explain its applications,in order to reflect the characters of LaBr3:Ce3+ crystal comprehensively.更多还原
