Manganese-enriched CsPbCl3 perovskite nanocrystals for self-assembled supercrystals

Abstract

The self-assembly of CsPbCl₃ perovskite nanocrystals and their Mn²⁺-enriched analogs into supercrystals is reported. Increasing Mn²⁺ content in the nanocrystals leads to formation of larger, increasingly uniform cubic supercrystals that eventually become rod-like with higher photoluminescence quantum yields.
