Claim 13:
14. A method of producing a light-emitting film, comprising
disposing a film comprising a plurality of semiconductor nanocrystals on a substrate, and
treating the plurality of semiconductor nanocrystals with a solution comprising an inorganic metal salt in a polar solvent to bind an anion of the inorganic metal salt to the plurality of semiconductor nanocrystals, and treating the plurality of semiconductor nanocrystals with a solution comprising a first organic ligand to bind the first organic ligand to the plurality of semiconductor nanocrystals,
wherein the inorganic metal salt comprises an inorganic metal halide, an inorganic metal sulfate, an inorganic metal nitrate, an inorganic metal thiocyanate, or a combination thereof, and
first organic ligand comprises a substituted or unsubstituted C6 to C30 aromatic ring group and a carboxylate group, a substituted or unsubstituted C3 to C30 aromatic heterocyclic group and a carboxylate group, or a combination thereof.
