摘要 |
<p>The present invention relates to a transparent electrode for an organic light emitting diode (OLED), comprising, on a transparent substrate made of mineral glass, n unit stacks of thin layers, each unit stack comprising successively, starting from the glass substrate, (a) a layer of mixed tin and zinc oxide (SnZnO), (b) a crystalline layer of zinc oxide (ZnO), optionally doped with aluminium, and (c) a layer of metallic silver, in contact with the ZnO layer, the electrode being characterised in that, between each layer of silver and the layer or layers of SnZnO closest thereto, a layer of silicon nitride (Si3N4) or of silica is arranged (d), optionally doped with a metal. The present invention also relates to an OLED device containing such an electrode and a method of manufacturing such a device.</p> |
