Phase Transformation Directed Mn 2+ Incorporation and Chiral Self‐Assembly Unlocks Tunable Multicolor and Circularly Polarized Light Emission in Metal Halide Perovskite Nanoparticles

ABSTRACT This study leverages the phase transformation of zero‐dimensional (0D), non‐emissive, cesium lead bromide (Cs 4 PbBr 6 ) nanoparticles (NPs) to introduce controlled manganese (Mn 2+ ), lead (Pb 2+ ), and halide ions (Br − ,Cl − ) to the perovskite matrix in a bid to engi...
