    Abstract: The present disclosure provides an electroluminescent device and a method for preparing the same, a display panel and a display device. The electroluminescent device includes a light emitting layer, a cathode layer, and an electron transport layer arranged between the light emitting layer and the cathode layer. The electron transport layer includes at least a first electron transport material and a second electron transport material that have different LUMO energy levels, and a ratio EM1/EM2 of the weight content of the first electron transport material to that of the second electron transport material decreases in a direction from a surface thereof proximate to the cathode layer to a surface thereof proximate to the light emitting layer. The electroluminescent device of the present disclosure can improve its efficiency and lifetime.
