Abstract: An electroluminescent device and a manufacturing method therefor are provided. The electroluminescent device includes an anode, a hole function layer, a quantum dot emission layer, an electron function layer, and a cathode that are sequentially stacked. The quantum dot emission layer is doped with a carrier transport material. The carrier transport material doped in the quantum dot emission layer not only can improve the conductivity of the quantum dot light emitting material and facilitate the injection and the transport of carriers, but also can increase the recombination probability of the carriers.
