Abstract

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.

Abstract

An organic electroluminescent device comprises a luminescent layer (3). The main material of the luminescent layer (3) comprises one of thermal activation delayed fluorescent materials, the main material is doped with dye, and the dye comprises at least one phosphorescent dye. The difference (ΔEST) between a triplet state energy level and a singlet state energy level is relatively small for the thermal activation delayed fluorescent material. The material is used as the fluorescent main part, and a part of a triplet state exciton energy level is transferred to a singlet state exciton, and the quantity of overall triplet state excitons is relatively small, so that the concentration of the triplet state excitons is reduced, and a recombination zone becomes narrow; therefore, the probability that an exciton enters a charge transport layer is effectively reduced, and narrowing of the recombination zone effectively prevents an N-type dopant from spreading to an exciton recombination zone. In addition, as the main material is used, the device corresponds to a relatively low working voltage.
