Ligand-engineered bandgap stability in mixed-halide perovskite LEDs

Nature, Published online: 03 March 2021; doi:10.1038/s41586-021-03217-8

The binding of multidentate ligands to the surface of lead halide perovskite nanocrystals suppresses the formation of surface defects that result in halide segregation, yielding materials with efficient and colour-stable red emission.
