Abstract:
Here, we report a room-temperature, post-synthetic Mn2+ doping method for perovskite nanocrystals (NCs) in non-polar solvents using zero-dimensional (0D) Cs4PbBr6 as a scaffold. The Pb2+-poor structure enables Mn2+ incorporation, inducing phase transition to CsPb1-xMnx(Cl/Br)3 with dual emission via oleylamine-mediated hydrogen-bond transfer.
