Fig. 5: Variation of antisolvent properties controls the dimensionality and thickness of anisotropic CsPbBr3 nanocrystals.
From: Antisolvent controls the shape and size of anisotropic lead halide perovskite nanocrystals
a Shape and thickness of the obtained perovskite nanocrystals depending on Cs-oleate to PbBr2 precursor ratio, relative antisolvent polarity and antisolvent volume. Acetone, the antisolvent used in the standard procedure of the nanorod and nanoplatelet synthesis and the typically injected volume are marked for reference (grey dashed lines). The type of nanocrystal product from each synthesis is indicated in the legend. b Shape anisotropy and ML (monolayer) thickness of perovskite nanocrystals classified by antisolvent properties (inert, weak, moderate, strong, and AX-selective solvents), legend as given in (a). Inert and weak solvents yield 2ML nanoplatelets, AX-selective solvents yield 3ML nanoplatelets. Strong solvents dissolve intermediate nanoclusters and do not yield any perovskite. Moderate solvents yield a variety of reaction products, with only acetone producing 3ML nanorods. Source data are provided as a Source Data file.
