Abstract: Techniques are provided for depositing a monolayer of nanoparticles over an OLED or comparable device. In combination with an enhancement layer disposed within a threshold distance of an emissive layer of the OLED, the nanoparticles may be used to provide a nanopatch antenna or otherwise improve the performance of the OLED.

Abstract: Disclosed is an OLED configuration that although comprises an exciplex that has an emission spectrum that is redder than the emission spectrum of the emitter, the emission from the exciplex is suppressed so that the overall OLED emission spectrum is still dominated by the emission of the emitter.

Abstract: An OLED is disclosed where the OLED includes, sequentially: an anode; a hole transporting layer; an emissive region; an electron transporting layer; and a cathode; where the emissive region includes a compound S1; and a compound A1. The compound S1 is an organometallic sensitizer that transfers energy to the compound A1, and the compound A1 is an acceptor that is an emitter in the emissive region. The compound S1 has a vertical dipole ratio (VDR) value greater than or equal to 0.2; and the compound A1 has a VDR value less than or equal to 0.2.

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 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.
