General description
溴化铯（CsBr）是一种无机化合物，水溶性适中，具有吸湿性。由于其有效的闪烁特性，CsBr晶体可用于检测辐射的闪烁计数器。它还在光学领域用作宽带分光光度计的分束器组件。
Application
溴化铯可用作：
- 提高锂离子电池中锂和石墨负极循环效率的电解质添加剂。铯离子可以帮助控制负极上的界面化学，从而提高性能。
- 一种添加剂，可通过钝化缺陷、改善电荷传输性能和提高功率转换效率来提高CsPbI2Br钙钛矿太阳能电池的效率和稳定性。
- 作为合成溴化铯铅（CsPbBr3）钙钛矿的前驱体材料，然后用作对称超级电容器中的电极材料。
- 作为制备热中子成像板的前驱体。
- 作为合成无铅CsBr的前驱体：用于制造白光LED的Eu2+纳米晶体。
- 作为制备CsI基闪烁体的添加剂。与溴化铯合金化可提高CsI晶体的屈服极限和显微硬度。
