Substrate for an organic light-emitting device, use and process for manufacturing this substrate, and organic light-emitting device
First Claim
1. A substrate for an organic light-emitting device, comprising, on a first main face, a bottom electrode film, the electrode film being formed from a thin-film multilayer coating comprising, in succession:
- a contact layer comprising at least one of zinc oxide and tin zinc oxide and no indiuma metallic functional layer having an intrinsic electrical conductivity property and a thickness of from 3 to 20 nm, wherein the metal functional layer comprises silver; and
an overlayer comprising at least one of the following, optionally doped, metal oxides;
molybdenum oxide, indium oxide, a mixed indium tin oxide, a mixed indium zinc oxide, and a mixed zinc tin oxide,wherein the substrate comprises a base layer, said base layer covering said main face and not comprising indium.

Abstract
A substrate for an organic light-emitting device, especially a transparent glass substrate, which includes, on a first main face, a bottom electrode film, the electrode film being formed from a thin-film multilayer coating comprising, in succession, at least: a contact layer based on a metal oxide and/or a metal nitride; a metallic functional layer having an intrinsic electrical conductivity property; an overlayer based on the metal oxide and/or a metal nitride, especially for matching the work function of said electrode film, said substrate including a base layer, said base layer covering said main face.
