摘要： Emissive layer structures for organic emissive devices and emissive devices containing such structures are provided. The emissive layer includes one or more sub-layers or similar regions. A fluorescent emitter and two compounds that may form an exciplex are distributed within the sub-layers so as to enhance Forster transitions from the exciplex to the fluorescent acceptor and suppress undesirable Dexter transitions from the exciplex to the fluorescent acceptor.

摘要： Disclosed is a device that includes an emissive material or region including a host that is doped with a first material as an emitter that is an acceptor and a phosphorescent-capable second material as a sensitizer. The first material and the second material each has a first singlet state and a first triplet state. The first triplet state of the second material is not lower than the first triplet state of the first material. The second material transfers excitons to the first material and the excitons that transition to the first triplet state of the first material can be activated to the first singlet state of the first material through a thermal activation process.
