    Abstract: Provided are compounds, formulations comprising compounds, and devices that utilize compounds, where the devices include a substrate, a first electrode, an organic emissive layer comprising an organic emissive material disposed over the first electrode. The device includes 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. The enhancement layer is provided no more than a threshold distance away from the organic emissive layer, where 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. At least one of the organic emissive material and the organic emissive layer has a vertical dipole ratio (VDR) value of equal or greater than 0.33.
