Traditional growth processes used to synthesize perovskite microcrystals often lack real-time monitoring capabilities, making it difficult to systematically capture the dynamic processes of nucleation, growth and morphology evolution. Here, the authors report a visual growth strategy based on water-induced phase transitions that enables real-time tracking and structural regulation of Cs4PbBr6-to-CsPbBr3 microcrystal transformation under ambient conditions, reducing experimental complexity and offering higher control precision.
