Abstract
A cathode stack with a getter layer is disclosed. The cathode stack includes an electron injection layer, a capping layer and a getter layer. An organic electroactive device including a cathode stack with a getter layer is also presented. A method of fabricating an electroactive device with a cathode stack including a getter layer is also provided.
Claims16
A cathode stack for organic electroactive devices comprising:
- an electron injection layer,
- a capping layer, and
- a getter layer, wherein the capping layer surrounds the getter layer from all sides and the capping layer is in contact with at least a portion of the electron injection layer.
An organic electroactive device comprising:
- at least one electroactive layer;
- and
- a cathode stack, wherein the cathode stack comprises:
- an electron injection layer;
- a capping layer;
- and
- a getter layer, wherein the capping layer surrounds the getter layer from all sides and the capping layer is in contact with at least a portion of the electron injection layer.
4 more elements
A method of making a cathode stack, the method comprising:
- providing an electron injection layer, a capping layer, and a getter layer in a stacked structure;
- wherein the capping layer surrounds the getter layer from all sides and the capping layer is disposed in contact with at least a portion of the electron injection layer.
