Application

Cesium bromide (CsBr) is commonly used in scintillation detectors, which are devices that detect and measure ionizing radiation. CsBr has also found applications in optoelectronic devices.
Cesium bromide finds application in synthesis of perovksites based photovoltaic materials. Our perovskite grade CsBr can readily be dissolved in DMF to yield 1M solution.

Halide perovskites have attracted much attention over the past 5 years as a promising class of materials for optoelectronic applications. However, compared to hybrid organic-inorganic perovskites, the study of their pure inorganic counterparts, like cesium lead halides (CsPbX3), lags far
Michael Kulbak et al.
The journal of physical chemistry letters, 7(1), 167-172 (2015-12-25)
Direct comparison between perovskite-structured hybrid organic-inorganic methylammonium lead bromide (MAPbBr3) and all-inorganic cesium lead bromide (CsPbBr3), allows identifying possible fundamental differences in their structural, thermal and electronic characteristics. Both materials possess a similar direct optical band gap, but CsPbBr3 demonstrates
