The invention discloses a quantum dot light-emitting layer preparation method, a quantum dot light-emitting diode, and a preparation method. The quantum dot light-emitting layer preparation method comprises the steps: preparing a quantum dot light-emitting layer; enabling the quantum dot light-emitting layer to be immersed into short chain ligand solution for 1s-10min through employing an in-situ ligand exchange method, taking out the quantum dot light-emitting layer, and then washing the surface of the quantum dot light-emitting layer through employing the solvent which is the same as the short chain ligand solution, so as to remove the residual short chain ligand. The method solves a problem that the quantum dot surface ligand affects the dispersibility through carrying out the in-situ ligand exchange of the quantum dot light-emitting layer. The method adjusts the space distance between quantum dots through the in-situ ligand exchange, and achieves the high-efficiency quantum dot light-emitting diode device through selecting the ligand with the optimal chain length. The method is simple through employing the in-situ ligand exchange method, is lower in implementation cost, and is suitable for the preparation of low-cost and large-size devices.
