Assignee: UNIVERSAL DISPLAY CORPORATION
Field: Semiconductors (Electrical engineering)
Classification: CPC H  Y | IPC H

Claim 0:
1. A device comprising:
a substrate;
a first electrode;
an organic emissive layer comprising an organic emissive material disposed over the first electrode; and
an enhancement layer, comprising a plasmonic material exhibiting surface plasmon resonance that non-radiatively couples to the organic emissive material and transfers excited state energy from the organic emissive material to the non-radiative mode of surface plasmon polaritons, disposed over the organic emissive layer,
wherein the enhancement layer is provided no more than a threshold distance away from the organic emissive layer, and
wherein the organic emissive material has a total non-radiative decay rate constant and a total radiative decay rate constant due to the presence of the enhancement layer, and the threshold distance is where the total non-radiative decay rate constant is equal to the total radiative decay rate constant.
