More Information
Summary:A quantum dot composite including a quantum dot and a quantum dot ligand located on a surface of the quantum dot is provided. The quantum dot ligand includes a hydrophilic linking portion including an oxygen atom, a bonding portion linked to one side of the linking portion and including different functional groups bonded to the quantum dot, and a terminal portion linked to the linking portion at a side opposite to the linking portion. The quantum dot ligand is configured to prevent or reduce aggregation of quantum dots and improve their dispersion in a solvent thereby improving the light and/or heat resistance of electronic apparatus that utilize the quantum dot composite.
