Abstract
A method for producing a quantum dot composition includes providing a preliminary quantum dot composition containing a quantum dot to which a ligand is bonded and a free ligand, providing an adsorbent to the preliminary quantum dot composition, adsorbing the free ligand to the adsorbent, and removing a modified adsorbent to which the free ligand is adsorbed to provide a purified quantum dot composition. A light emitting element including the purified quantum dot composition may have superior luminous efficiency.
