Abstract In this work, we develop an environmental-friendly approach to produce organic-inorganic hybrid MAPbBr 3 (MA = CH 3 NH 3 ) perovskite nanocrystals (PeNCs) and PMMA-MAPbBr 3 NC films with excellent compression-resistant PL characteristics. Deionized water is used as the solvent to synthesize MAPbBr 3 powder instead of conventionally-used hazardous organic solvents. The MAPbBr 3 PeNCs derived from the MAPbBr 3 powder exhibit a high photoluminescence quantum yield (PLQY) of 93.86%. Poly(methyl methacrylate) (PMMA)-MAPbBr 3 NC films made from the MAPbBr 3 PeNCs retain ∼97% and ∼91% of initial PL intensity after 720 h aging in ambient environment at 50 °C and 70 °C, respectively. The PMMA-MAPbBr 3 NC films also exhibit compression-resistant photoluminescent characteristics in contrast to the PMMA-CsPbBr 3 NC films under a compressive stress of 1.6 MPa. The PMMA-MAPbBr 3 NC film integrated with a red emissive film and a blue light emitting source achieves an LCD backlight of ∼114% color gamut of National Television System Committee (NTSC) 1953 standard.more » « less
