  • Publication number: 20200295289
    Abstract: An organic light-emitting diode including an anode, a cathode, and a luminescent layered structure disposed between the anode and the cathode. The luminescent layered structure has a luminescent layer, a sensitizer layer and a guiding material. The luminescent-layer singlet state is two times higher than the luminescent-layer triplet state. The sensitizer layer has a sensitizer-layer triplet state between the luminescent-layer singlet state and the luminescent-layer triplet state. The guiding material has a guiding-material triplet state between the sensitizer-layer singlet state and the sensitizer-layer triplet state. The energy of molecules at the sensitizer-layer singlet state is transferred to the guiding-material triplet state and then to the sensitizer-layer triplet state, which is then transferred to the luminescent-layer triplet state and triggers triplet-triplet annihilation upconversion in the luminescent layer such that the luminescent layer emits light of a first color.
