  • Patent number: 9941482
    Abstract: This invention provides an organic electroluminescent device, a method of preparing the same, a display substrate comprising the same, and a display apparatus. According to the invention, the agglomeration and self quenching of quantum dots can be effectively prevented as the quantum dots are uniformly dispersed in electroluminescent polymer fibers. Due to the fluorescence resonance energy transfer effect between the electroluminescent polymer and the quantum dots, a higher quantum yield is achieved, and the luminescence efficiency of the quantum dots can be improved accordingly. Furthermore, since the light emission from the quantum dots is achieved by the fluorescence resonance energy transfer effect, which is an energy transfer process without damage to the quantum dots, the damage to quantum dots is less and thus the lifetime thereof can be beneficially increased, as compared to the direct charge injection mode of the prior art.
