1. An electroluminescence light-emitting device for generating an optical wavelength, the device comprising:
- a substrate;
an ITO layer posed on the substrate;
at least one pair of opposed and contacting light-emitting layers creating an interface with each light-emitting layer emitting light of an optical wavelength different from each other light-emitting layer, each interface emitting light of an optical wavelength different from the light emitted from the light-emitting layers and the interface of any other pair of opposed light-emitting layers; and
a metal electrode formed on an upper light-emitting layer of at least one pair of light-emitting layers; and
whereinthe ITO layer is an anode and the metal electrode is a cathode and each light-emitting layer is formed from an organic polymer.
