A series of Cs_0.2Rb_0.8Ca_1–xEu_xBr₃ (0 ≤ x ≤ 0.08) crystals doped with different concentrations of Eu²⁺ were grown using the Bridgman-Stockbarger method. The work describes the influence of Eu²⁺ concentration on the luminescent and kinetic properties of Cs_0.2Rb_0.8Ca_1–xEu_xBr₃ crystals, as well as on their scintillation performance. The maximum in the radioluminescence spectra of these crystals shifts from 439 to 446 nm with increasing europium concentration. The scintillation decay times of Cs_0.2Rb_0.8Ca_1–xEu_xBr₃ lengthen with the Eu²⁺ content. The best light output of 33600 photons/MeV is obtained for Cs_0.2Rb_0.8Ca_0.93Eu_0.07Br₃, and the best energy resolution of 6.9% is found for Cs_0.2Rb_0.8Ca_0.94Eu_0.06Br₃.

使用 Bridgman-Stockbarger 方法生长了 一系列掺杂有不同浓度 Eu ²⁺的 Cs _0.2 Rb _0.8 Ca _{1– x} Eu _x Br ₃ (0 ≤  x ≤ 0.08) 晶体。该工作描述了 Eu ²⁺浓度对 Cs _0.2 Rb _0.8 Ca _{1– x} Eu _x Br ₃的发光和动力学特性的影响晶体，以及它们的闪烁性能。随着铕浓度的增加，这些晶体的辐射发光光谱的最大值从 439 到 446 nm。Cs _0.2 Rb _0.8 Ca _{1– x} Eu _x Br ₃的闪烁衰减时间随着Eu ²⁺含量的增加而延长。Cs _0.2 Rb _0.8 Ca _0.93 Eu _0.07 Br ₃的最佳光输出为33600 photons/MeV ，Cs _0.2 Rb _0.8 Ca _0.94 Eu _0.06 Br的最佳能量分辨率为6.9%₃ .
