Highly Emissive Divalent-Ion-Doped Colloidal CsPb_1–<i>x</i>M_<i>x</i>Br₃ Perovskite Nanocrystals through Cation Exchange

Abstract

cation exchange and is observed to scale linearly with the lattice contraction. This work opens up new possibilities to engineer the properties of halide perovskite NCs, which to date are demonstrated to be the only known system where cation and anion exchange reactions can be sequentially combined while preserving the original NC shape, resulting in compositionally diverse perovskite NCs.
