Abstract
A method of exchanging ligands includes a step of mixing a QD composition in which intermediate ligands and QDs are dissolved in a water solvent with a target-ligand-substituting solvent in which target ligands are dissolved, to replace the intermediate ligands with the target ligands. The target ligands do not dissolve in the water solvent and are soluble in different solvents depending on whether or not the target ligands are coordinated to the QDs, and the target-ligand-substituting solvent dissolves the target ligands not coordinated to the QDs and does not dissolve the target ligands coordinated to the QDs.
