Abstract
Official abstract text for this publication.
The subject of the present invention is a multilayer electrode ( 3 ), 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 ( 10 ), successively comprises: —a contact layer ( 31 ) based on a metal oxide and/or a metal nitride; a functional metallic layer ( 32 ) having intrinsic electrical conductivity properties; a thin blocking layer ( 32 ) 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 ( 34 ) for adapting the work function.
First claim
Opening claim text (preview).
The invention claimed is: 1. A substrate with electrode for an organic light-emitting device, comprising: a substrate; and a multilayer bottom electrode formed on a first main face of the substrate; wherein: the multilayer bottom electrode comprises the following layers provided in succession on the first main face of the substrate: a contact layer comprising at least one of a metal oxide and a metal nitride; a metallic functional layer comprising silver, said metallic fu…
