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.
