The invention relates to a light-emitting device, in particular a light-emitting diode, with an arrangement of layers on a substrate, wherein the arrangement of layers has an anode contact and a cathode contact which are in electrical contact with a light-emitting layer stack arranged between the anode contact and the cathode contact which, on its part, comprises a polymer layer consisting of a polymer material and a low-molecular layer of vacuum-deposited small molecules of an organic material, and wherein the small molecules of the low-molecular layer are formed as donor molecules with an oxidation potential versus Fc/Fc+ (ferrocent/ ferrocenium redox couple) of maximum approx. -1.5V, if the low-molecular layer is arranged adjacent to the cathode contact, and as acceptor molecules with a reduction potential versus Fc/Fc+ (ferrocene/ ferrocenium redox couple) of minimum approx. -0.3 V if the low-molecular layer is arranged adjacent to the anode contact. |
