Abstract
The present invention provides a light-emitting diode. The light-emitting diode includes: an emissive layer, an electron transportation layer and a hole transportation layer that are respectively set in contact with upper and lower surfaces of the emissive layer, a first electrode set in contact with the hole transportation layer, and a second electrode set in contact with the electron transportation layer; and the electron transportation layer is formed of a material comprising graphene so that the excellent electrical conduction property and heat conduction capability of the graphene material help improve the heat dissipation capability and electron transportation capability of the light-emitting diode the electron transportation layer so as to enhance the service life and lighting efficiency of the light-emitting diode.
