| Abstract Scope |
There is great interest to prepare perovskite nanocrystals environmental-friendly. In this work, we develop a green route to synthesize CH3NH3PbBr3 nanocrystals with deionized water as precursor solvent. The prepared CH3NH3PbBr3 nanocrystals exhibit a PL peak at 511 nm and a photoluminescence quantum yield (PLQY) of 89.9%. Using the CH3NH3PbBr3 nanocrystals, we prepare poly(methyl methacrylate)-MAPbBr3 NC films. The PMMA-NC films can retain ~89.2% of its initial PL intensity after 720 h aging at 50 °C and 70 °C, respectively. The method developed in this work provides a simple technique to prepare CH3NH3PbBr3 nanocrystals environmental-friendly.
