ABSTRACT:
A method of making an OLED device capable of emitting light through the top electrode of such device includes providing a substrate and an anode over the substrate; providing an emissive layer disposed over the anode; providing first and second layers over the emissive layer with the first layer being in contact with the emissive layer or electron-transport layer and having a compound that includes an electron-injecting element, and the second layer having a reactive metal, and wherein such reactive metal reacts with the compound to release the electron-injecting element that dopes the interfacial region of the emissive layer or electron-transport layer to improve electron-injection and also reduces the reflectivity of the first and second layers is reduced; and providing a transparent conducting non-metallic top electrode over the second layer.
