  • Patent number: 12295199
    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.

  • Patent number: 12262636
    Abstract: The present disclosure discloses an organic electroluminescent device and a preparation method thereof. The device includes a light-emitting layer, the light-emitting layer includes a host material, an auxiliary host material and a fluorescent dye; the host material is an exciplex prepared by mixing an electron donor material and an electron acceptor material, the auxiliary host material is a thermally activated delayed fluorescence material, a singlet energy level and a triplet energy level of the exciplex are higher than the single energy level and triplet energy level of the auxiliary host material. The above organic electroluminescent device can promote the reverse intersystem crossing of the host material and the auxiliary host material from the triplet excitons to the singlet excitons, enhance the Foster energy transfer, reduce the triplet exciton quenching, therefore the efficiency roll-off of the device is small and the external quantum efficiency is high.
