International Classification:

H01L 51/50
H01L 51/52

Abstract:

Organic emissive devices are provided that include host structures with electron and/or hole transporting components having specific energy levels that promote good charge balance and enhanced charge capture. The disclosed energy level structures provide host systems that reduce exciplex formation and thereby promote improved device internal quantum efficiency and stability, or which intentionally include exciplex formation so as to modify the average orientation of the dipole.

International Classification:

H10K 50/85
H10K 50/11
H01L 33/44

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.
