The water–dimethylformamide (DMF)–dimethylsulfoxide (DMSO) system provides an ideal solution environment for the direct growth of pure‐phase emissive Cs 4 PbBr 6 crystals, in which Cs + is effectively dissolved. Reversible phase transitions between Cs 4 PbBr 6 , CsPbBr 3 and CsPb 2 Br 5 can be controlled by varying the amount of water and DMSO in the three‐solvent system. This three‐solvent‐based synthetic approach enables an economical, robust, and large‐scale production for all‐inorganic cesium lead bromide perovskites.
