Inorganic cesium manganese halides: Insights into optical properties, coordination chemistry, synthesis methods and optoelectronic applications
Year: 2025
Type: article
Abstract: In recent years, remarkable progress has been made in research on cesium manganese halides. These materials have sparked intense research interest in applications that require rapid response rates, such as X-ray scintillation and optical communication, due to their high PLQY and tunable radiative lifetimes depending on the shortest Mn-Mn distance. This review aims to provide an in-depth and exclusive review of cesium-Mn metal halides with respect to their optical, electronic, and spectroscopic properties, as well as their coordination chemistry. We explain the ion-luminescence emission mechanism and its dependency on the local coordination around the Mn 2+ ions. Fundamental principles such as Mn-Mn coupling interactions, Mn-Mn distance, and d–d transition selection rules are discussed in depth. Then, we discuss the three most common protocols for synthesizing Mn halide perovskites. In conclusion, we provide perspectives to establish a clear and comprehensive understanding to optimize the structure-luminescence relationship to pioneer strategies to overcome challenges in cesium-Mn halides and develop optoelectronic devices.
