ZWEISCHICHTIGE ELEKTRONENINJEKTIONSELEKTRODE ZUR VERWENDUNG IN EINER ELEKTROLUMINESZENZVORRICHTUNG

摘要

An electroluminescent device comprising an anode, an electroluminescent layer, and a cathode. The cathode includes a fluoride layer contacting the electroluminescent layer, a conductive layer contacting the fluoride layer, and the thickness of the fluoride layer being selected so that the bilayer acts as an electron injecting contact, the bilayer providing stability against atmospheric corrosion.
