We report a general synthetic method that affords all-inorganic perovskite nanocrystals of varied dimensionalities, including Cs4PbBr6, CsPb2Br5, and CsPbBr3. The as-synthesized NCs exhibit a narrow size distribution, high phase purity, and high photoluminescence quantum yield (PLQY, ~84%). Importantly, this single-synthetic approach endows nanocrystals with an identical capping agent, allowing for the parallel measurement of optical and electronic properties without interference from surface discrepancy. Our strategy introduces many possibilities for comparative studies on the intrinsic properties of these emerging all-inorganic perovskite nanocrystals​.
