Abstract
A thin non-conductive fluorocarbon polymer layer is advantageously used in electroluminescent devices. The polymer is produced by plasma polymerization of a fluorocarbon gas in a RF plasma
Claims18
An electroluminescent device comprising:
- a) a substrate formed of an electrically insulating material which can be either an optically transparent material or an opaque material;
- b) a conductive anode mounted over the substrate;
- c) a thin polymer layer on the conductive anode prepared by RF plasma polymerization of a fluorocarbon gas wherein the thickness of the thin fluorocarbon layer is in a range of 0.2 to 3 nm;
- d) an organic light-emitting structure formed over the polymer layer;
- and
- e) a cathode formed over the organic light-emitting structure.
