Electroluminescent devices

摘要

An electroluminescent device comprising:
an anode electrode layer;
a layer comprising doped PEDOT over the anode electrode layer;
a semiconducting region over the anode electrode layer, the semiconducting region comprising a first semiconducting organic layer comprising a first semiconducting organic component adjacent to a second semiconducting organic layer comprising a second semiconducting organic component, the first semiconducting layer being disposed between the layer of doped PEDOT and the second semiconducting layer; and
a cathode electrode layer over the semiconducting region,
wherein the first semiconducting organic layer is capable of hole transport and wherein the second semiconducting organic layer is light emissive.
