  • METHOD FOR TREATING ARTHRITIS BY USING STEM CELL PREPARATION AND METHOD FOR PREPARING STEM CELL PREPARATION
    Publication number: 20230201266
    Abstract: The present disclosure provides a method for treating arthritis by using a stem cell preparation. The stem cell preparation of the present disclosure can effectively delay cartilage degeneration caused by arthritis, and it is confirmed by whole blood analysis and blood biochemical analysis that the stem cell preparation in the form of three-dimensional stem cell spheres provides a safe treatment for arthritis. The present disclosure also provides a method for preparing the stem cell preparation.

  • Organic light-emitting diode with enhanced light-emitting efficiency and color purity
    Patent number: 10784458
    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.

  • ORGANIC LIGHT-EMITTING DIODE
    Publication number: 20200227671
    Abstract: An organic light-emitting diode including an anode, a cathode, and a luminescent layered structure is provided. The luminescent layered structure is disposed between the anode and the cathode. The luminescent layered structure has a luminescent layer and a sensitizer layer. The luminescent layer has a luminescent-layer ground state, a luminescent-layer singlet state and a luminescent-layer triplet state, in which two times of the luminescent-layer triplet state is higher than the luminescent-layer singlet state. The sensitizer layer has a sensitizer-layer triplet state, which is between the luminescent-layer singlet state and the luminescent-layer triplet state.

The sensitizer layer has a sensitizer-layer triplet state, which is between the luminescent-layer singlet state and the luminescent-layer triplet state. The molecules of the sensitizer layer at the sensitizer layer triplet layer transfers energy to the molecules of the luminescent layer at 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.
