Lead-Doped Cesium Manganese Halide Perovskite Nanocrystals for Light-Emitting Diodes: Room-Temperature Synthesis, Energy Transfer, and Phase Modulating
Lead halide perovskite nanocrystals (NCs) have been attracting the interest of researchers due to their outstanding photophysical properties. However, their practical application is greatly hindered by lead toxicity. Despite series of lead-free NCs being investigated, they generally exhibit broadband emission and poor color tunability. Herein, we proposed a facile room temperature synthesis of highly efficient color-tunable CsMnBr3:Pb2+ NCs. Ascribing to the efficient energy transfer from [PbBr6]4– to Mn2+, the photoluminescent quantum yield (PLQY) of CsMnBr3:Pb2+ NCs reaches up to 83.6%, which is 12.5 times that of undoped CsMnBr3 NCs. More interestingly, the red-emitting CsMnBr3:Pb2+ NCs could be easily transformed to green-emitting Cs3MnBr5:Pb2+ NCs through coordination modulating. The color-tunable CsMnBr3:Pb2+ NCs and Cs3MnBr5:Pb2+ NCs possess high PLQY and high color purity, demonstrating great application potential in optoelectronic fields.
