Abstract
The subject of the present invention is a multilayer electrode (), acid etching thereof and also organic light-emitting devices incorporating it. The multilayer electrode, known as a lower electrode for an organic light-emitting device (), successively comprises: —a contact layer () based on a metal oxide and/or a metal nitride; a functional metallic layer () having intrinsic electrical conductivity properties; a thin blocking layer () directly on the functional layer, the layer comprising a metallic layer having a thickness less than or equal to 5 nm and/or a layer with a thickness less than or equal to 10 nm, which is based on a substoichiometric metal oxide, substoichiometric metal oxynitride or substoichiometric metal nitride; a coating comprising an overlayer based on a metal oxide () for adapting the work function.
