Abstract: Device structures are provided that include one or more plasmonic OLEDs and zero or more non-plasmonic OLEDs. Each plasmonic OLED includes an enhancement layer that includes a plasmonic material which exhibits surface plasmon resonance that non-radiatively couples to an organic emissive material and transfers excited state energy from the emissive material to a non-radiative mode of surface plasmon polaritons in the plasmonic OLED.

Abstract: Organic electroluminescent devices are provided, including devices having a tandem structure in which two or more plasmonic OLEDs are arranged in a stack. The plasmonic OLEDs may be inverted or non-inverted. A common electrode disposed between the OLEDs or an outer electrode of the device provides the enhancement layer for one or plasmonic OLEDs in the stack.

Abstract: Light emitting devices are provided that include an outcoupling layer in which asymmetric nanoparticles are disposed, where the nanoparticles are aligned such that the difference between each nanoparticle's major axis and the average direction of the major axes of all nanoparticles is minimized. The use of aligned, physically asymmetric nanoparticles leads to improved outcoupling and performance of the device.
