Cesium–lead halide perovskite nanomaterials have been considered new-generation emitters that can meet the requirements of high photoluminescence efficiency and color standard Rec. 2020. However, their practical application is currently hindered by challenge achieving better stability growth in green solvents. In this study, we propose a green-solvent ligand-free strategy to achieve highly photoluminescent stable phosphors confining them within mesoporous zeolite. The whole process because water only solvent. molecular sieve confines nanocrystals passivates defects perovskites H-bonding interactions. as-synthesized perovskite-mesoporous zeolite show PLQY 81.5% good against oxygen, water, heat. Besides, fabricated white LED devices exhibit wide gamut (145% for NTSC 108% 2020) with coordinates (0.333, 0.334). This zeolite-confined synthesis method offers promising developing luminescent materials.
