Recent trends in synthesis, properties, and applications of CsPbX3 quantum dots: A review

All inorganic Cesium lead halide perovskite quantum dots (CsPbX3 QDs, X = Cl, Br, I) have sparked a great interest due to their remarkable properties and wide range of applications in optoelectronic devices. These perovskite quantum dots exhibit unique characteristics such as high photoluminescence quantum yield, tunable emission, narrow emission spectrum, and high carrier mobility, making them highly desirable for luminescent applications. Moreover, the introduction of various strategies aimed at enhancing stability and photoluminescent properties, along with the utilization of all-inorganic compositions, has established a resilient foundation for the development of ambient-stable quantum dot devices. This review reports recent advancements in CsPbX3 quantum dots, encompassing their structure, synthesis methods, and morphological and optical properties. Furthermore, we discuss the emerging applications of inorganic perovskite quantum dots in quantum light-emitting diodes, solar cells, nanolasers, and in electronics, highlighting their potential as key components in next-generation optoelectronic technologies.
