  The present invention discloses an organic electroluminescent device and a manufacturing method thereof. The host material of the light-emitting layer of the organic electroluminescent device is material in which the triplet state energy level of the CT excited state is higher than that of the n-π excited state by 0 to 0.3 eV; or the triplet state of the host material of the light-emitting layer is higher than that of the n-π excited state by more than 1.0 eV; in addition, the difference in energy level between the second triplet state of the n-π state and the first singlet state of the CT excited state is −0.1 to 0.1 eV; and the luminescent dye is a fluorescent dye. With regard to the organic electroluminescent device in the present invention, as new host material in the light-emitting layer is used and the host material has a donor group and an acceptor group, the triplet state in the light-emitting layer may be fully utilized to achieve a 100% light-emitting efficiency in the fluorescent device. Furthermore, no noble metal is required to be used, thus reducing the cost.

  The present invention discloses an organic electroluminescence device, comprising a luminescent layer, wherein, a host material of the luminescent layer comprises a thermally activated delayed fluorescence material, the host material is doped by a dye, and the dye comprises at least one phosphorescent dye. The present invention employs a thermally activated delayed fluorescence material, whose difference between the triplet state energy level and the singlet state energy level (ΔE ST ) is relatively small. The present invention employs the material as the phosphorescence host, so part of the triplet state exciton level transfers to the singlet state excitons, and the amount of the overall triplet state excitons is smaller. Therefore, the concentration of the triplet state excitons decreases, and the recombination region becomes narrower, which effectively reduces the probability of excitons entering the charge transport layer, and at the same time the narrowing of the recombination region effective prevents the diffusion of N-type dopants into the exciton recombination region. Additionally, by employing the host material, the device corresponds to a low working voltage.
