Abstract
The invention relates to highly stable nanostructures with inorganic ligands for electroluminescent devices, particularly nanostructure composition comprising at least one population of nanostructures; and at least one fluoride containing ligand bound to the surface of the nanostructure; wherein the fluoride containing ligand is selected from the group consisting of a fluorozincate, tetrafluoroborate, and hexafluorophosphate. The invention also relates to highly stable nanostructures comprising at least one population of nanostructures and fluoride anions bound to the surface of the nanostructure. The invention also relates to methods of producing such nanostructures.
