TLDR
In this article, an ultrathin LiF layer adjacent to an electron-transporting layer and an aluminum outerlayer was used as an electrode for organic electroluminescent devices.Abstract:
A bilayer is used as an electrode for organic electroluminescent devices The bilayer consists of an ultrathin LiF layer adjacent to an electron-transporting layer and an aluminum outerlayer Devices with the bilayer electrode showed enhanced electron injection and high electroluminescence efficiency as compared with a Mg09Ag01 cathode Similar effects were observed when replacing MgO for LiF The improvements are attributed to band bending of the organic layer in contact with the dielectricsread more
