WebGreen-emitting Cs4PbBr6 nanocrystals were synthesized by the water-assisted solid-state reaction method for the first time. Although CsPbBr3 phases were observed in the X-ray diffraction (XRD) patterns of the perovskite nanocrystal samples as impurities, the XRD patterns of the samples could be well indexed WebThe optical phonon modes in Cs4PbBr6 NCs can be assigned to both Pb-Br stretching and rocking motions from density functional theory calculations. Our results address the origin of the dual broadband Pb2+ ion emissions observed in Cs4PbBr6 NCs and provide insights into the mechanism of ionic exciton-optical phonon interactions in these 0D ...
