Room temperature preparation of highly stable cesium lead halide perovskite nanocrystals by ligand modification for white light-emitting diodes

The poor stability of halide perovskite nanocrystals (NCs) has severely hindered future practical application. Herein, we proposed a facile and effective ligand modification route to synthesize stable CsPbBr 3 nanocrystals by introducing a double-terminal ligand, namely 4,4′-Azobis(4-cyanovalericaci...
