Abstract:
Disclosed is an electroluminescence light-emitting device for generating an optical wavelength, comprises a substrate; an ITO layer coated on the substrate, at lest two light-emitting layers sequentially formed on the ITO layer and having a different band gap, and a metal electrode formed on an upper light-emitting layer of the at least two light-emitting layers, wherein the ITO layer is used as an anode and the metal electrode is used as a cathode.
