Growth mechanism of strongly emitting CH3NH3PbBr3 perovskite nanocrystals with a tunable bandgap

Abstract

The development of perovskite nanocrystals is limited by poor mechanistic understanding of their growth. Here, the authors systematically study the ligand-assisted reprecipitation synthesis of CH3NH3PbBr3 nanocrystals, revealing the effect of precursor and ligand concentrations on bandgap tunability.
