Partial ligand exchange on CsPbI3 nanocrystals with alkyl phosphonium iodide improves phase stability and emission efficiency in light-emitting diodes

All-inorganic colloidal CsPbI3 nanocrystals are promising materials for light-emitting applications owing to their excellent optoelectronic properties. However, their practical implementation remains limited by surface defects, ligand instability, and phase degradation under ambient conditions. Here, we employ trimethy...
