Synthesis of highly calibrated CsPbBr₃ nanocrystal perovskites by soft chemistry

A new synthetic method for preparing highly calibrated CsPbBr₃ nanocrystal perovskites is described and analyzed using high-resolution scanning transmission electron microscopy. This new method based on soft chemistry leads to the large-scale production of nanocrystals. Such monodisperse nanocrystals allow for the deposition of homogeneous films, which provides new opportunities for the next generation of optoelectronic devices.
