LaBr_3:Ce^(3+)闪烁晶体研究进展

The Rsearch Progress of LaBr_3:Ce^(3+) Scintillator Crystal

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。

The cerium doped lanthanum bromide crystal（LaBr3 ：Ce^3＋） 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 ： Ce^3＋ crystal to NaI（Tl）, and list examples to explain its applications, in order to reflect the characters of LaBr3 ：Ce^3＋ crystal comprehensively.
