| description | The invention belongs to the technical field of perovskite quantum dots, and particularly relates to a perovskite quantum dot with a coating shell, a preparation method of the perovskite quantum dot and a quantum dot device. According to the method, in the synthesis step of adding an aluminum source which is strongly combined with halogen as a ligand into the perovskite quantum dot, an aluminum-containing ligand is anchored by using halogen sites on the surface of the quantum dot; then the aluminum oxide shell is changed into a compact aluminum oxide shell through a reaction environment, and the passivation effect and the lattice stabilizing effect of the ligand are enhanced by utilizing the strong interaction between aluminum and halogen. The aluminum ligand can form an aluminum oxide shell by utilizing a post-treatment means, and is firmly anchored on the surface of the quantum dot by taking a halogen site on the surface of the quantum dot as an active site, so that the interaction between the core and the |
