  • Patent number: 10957870
    Abstract: A region of a device is provided that includes a first material and a second material. The first and second materials may be co-dopants of an emissive material or region. The first material may have an energy gap of not more than about 100 meV between the first excited singlet state and the first excited triplet state. Excitons that transition to the T1 state can be activated to the S1 state due to the relatively small energy gap. This thermal activation process is fast enough that non-radiative decay from the T1 state to the S0 state is minimal or negligible, thus allowing for sensitization up to and including 100%. The second material may be a phosphorescent-capable material, and may act as a sensitizer to the first material.

  • Publication number: 20210066637
    Abstract: 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.
