ENERGY LEVELS AND DEVICE STRUCTURES FOR PLASMONIC OLEDS

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.
