摘要： An organic electroluminescent device includes at least one luminescent layer, constituted from an organic compound, provided between a cathode electrode and an anode electrode opposed to the cathode electrode; and an organic compound layer doped with a metal capable of acting as an electron-donating dopant, the organic compound layer being disposed as a metal doping layer in an interfacial surface with the cathode electrode. An emission spectrum of light emitted from the organic electroluminescent device is controlled by varying a layer thickness of the metal doping layer. Alternatively, the organic compound layer can be doped with an electron-accepting compound, disposed as a chemical doping layer in an interfacial surface with the anode electrode on the luminescent layer side; wherein an emission spectrum of light emitted from the organic electroluminescent device is controlled by varying a layer thickness of the chemical doping layer.

摘要： An organic electroluminescent device includes at least one light emission layer from an organic compound, the light emission layer being positioned between an anode electrode and a cathode electrode opposed to the anode electrode, in which an organic layer positioned adjacent to the anode electrode is from an organic compound which includes, as an electron-accepting dopant, an electron-accepting compound having a property of oxidizing the organic compound of said organic layer, said electron-accepting compound being doped to said organic layer in vacuum with a simultaneous evaporation method.
