Here we develop a method, namely, room-temperature liquid diffused separation induced crystallization that uses silicone oil to separate the solvent from the perovskite precursors, to grow high-quality perovskite single crystals. The growth kinetics of perovskite single crystals using this method is elucidated, and their structural and optoelectronic properties are carefully characterized. The resultant perovskite single crystals, taking CH₃NH₃PbBr₃ as an example, exhibit approximately 1 µs lifetime, a low trap density of 4.4 × 10⁹ cm^-3, and high yield of 92%, which are appealing for visible light or X-ray detection. We hope our findings will be of great significance for the continued advancement of high-quality perovskite single crystals, through a better understanding of growth mechanisms and their deployment in various optoelectronics. The diffused separation induced crystallization strategy presents a major step forward for advancing the field on perovskite single crystals.Nature communicationsRoom-temperature liquid diffused separation induced crystallization for high-quality perovskite single crystals.PMC7055282618751542019AAA0202018CFA0212019CFB122Li WLin QGui PFang GTao CLi RLi BLiu CYao FPeng J45falseRoom-temperature liquid diffused separation induced crystallization for high-quality perovskite single crystals.Large single crystals serve as an ideal platform for investigating intrinsic material properties and optoelectronic applications.
