用脱氧剂非真空环境下、Ｓｔｏｃｋｂａｒｇｅｒ方法生长未掺和掺钆和铕的、浓度范围在０．１～０．２ｗｔ％的ＰｂＦ２：β晶体．本文报导Ｘ射线激发ＰｂＦ２：Ｇｄ晶体的Ｇｄ３＋发射．揭示了分别来自６Ｐ和６Ｉ多重态３１２．５和２７７．４ｎｍ发射带，而６Ｄ→８Ｓ发射被点阵再吸收．６Ｉ的发射强度低于６Ｐ，说明６Ｐ能级优先占据．室温下以Ｘ射线激发在３６８．９和８１４．５ｎｍ之间观察到１４条Ｅｕ３＋离子的荧光线，并指定这些立方Ｅｕ３＋位荧光线．其中，△Ｊ＝１磁偶极线非常强．ＰｂＦ２：０．２ｗｔ％Ｇｄ２Ｏ３的总的发射强度稍高于ＰｂＦ２：０．１ｗｔ％Ｇｄ２Ｏ３．但是，对于ＰｂＦ２：０．２ｗｔ％Ｅｕ２Ｏ３和ＰｂＦ２：０．１ｗｔ％Ｅｕ２Ｏ３，他们总的发射强度相近．
The undoped gadolinium-doped and europium-doped PbF2: β crystals were grown in a concentration range of 0.1-0.2 wt% with a deoxidizer under non-vacuum environment using Stockbarger method. This article reports X-ray excitation of Gd3 + emission in PbF2: Gd crystals. Revealed 312.5 and 277.4 nm emission bands from the 6P and 6I multiplets, respectively, while the 6D → 8S emission was lattice-absorbed. 6I emission intensity is lower than 6P, indicating 6P level priority to take. Fluorescence spectra of 14 Eu3 + ions were observed between 368.9 and 814.5 nm by X-ray excitation at room temperature, and these cubic Eu3 + fluorescence lines were assigned. Among them, △ J = 1 magnetic dipole is very strong. The total emission intensity of PbF2: 0.2wt% Gd2O3 is slightly higher than that of PbF2: 0.1wt% Gd2O3. However, their total emission intensities are similar for PbF2: 0.2 wt% Eu2O3 and PbF2: 0.1 wt% Eu2O3.
