However, the materials for growing perovskite NCs are insoluble or hydrolyzed in most green solvents, limiting their further development. Based on rational chemical analysis, an alkali-metal-assisted green-solvent synthesis method for in situ growth of CsPbBr₃ NCs within SAPO-34 zeolite with bright luminescence is developed. Water is the only solvent used in the whole process. Surprisingly, by the synergistic effect of the channel structure of SAPO-34 and alkali-metal ions crystallization regulation, the CsPbBr₃ NCs embedded in SAPO-34 assisted by Na⁺ emit bright blue light under ultraviolet illumination, with a 30 nm blue shift comparing to the CsPbBr₃ NCs assisted by K⁺. Moreover, CsPbBr₃ NCs can also be grown in mesoporous SiO₂ SBA-15 and zeolites including ZSM-5, AlPO-5, and SOD, indicating that the method is universal for in situ growth of luminescent perovskite NCs in porous materials. This alkali-metal-assisted green-solvent synthesis provides a new strategy for developing high-quantum-yield, tunable-emission, and stable perovskite luminescent materials.Advanced science (Weinheim, Baden-Wurttemberg, Germany)Alkali-Metal-Assisted Green-Solvent Synthesis for In Situ Growth of Perovskite Nanocrystals in Porous Materials.PMC1096652362174103B21005SYJS2022052022JQ-3742022JQ-552XDA21061001U21A20102XDA21061002Wang PHe TWang BLiu SFZhang HZhang LLi NfalseAlkali-Metal-Assisted Green-Solvent Synthesis for In Situ Growth of Perovskite Nanocrystals in Porous Materials.Inorganic metal halide perovskite CsPbX₃ (X = I, Br, and Cl) nanocrystals (NCs) are rapidly developed due to their excellent photophysical properties and potential applications in lighting, lasers, and scintillators.
