Abstract: The present disclosure relates to a light emitting diode in which a charge transfer layer, which disposed between two electrodes, including an inorganic material in which an amphiphilic ligand is connected to a surface of an inorganic nano particle and to a light emitting device having the diode. The amphiphilic ligand minimizes defects on the surface of the inorganic nano particle, thus charge transfer materials can be stably. Since charge transfer layers and an emitting material layer can be prepared by using an orthogonal solvent, interface morphology between the emissive layers can be improved.

Abstract: A multi-emission quantum dot includes a first core having a first thickness along an axis from a first surface to a second surface of the first core, a first shell enclosing the first core, a second core surrounding the first shell. The second core may has a second thickness along the same axis smaller than the first thickness. The quantum dot also includes a second shell enclosing the second core. The first core may be configured to emit light of a first color, and the second core may be configured to emit light of a second color different from the first color.
