description The invention provides a preparation method of passivated inorganic perovskite nanocrystals, which belongs to the technical field of nanomaterials, and comprises the following steps: synthesizing an inorganic lead halide perovskite nanocrystal colloidal solution by using a high-temperature injection method, then mixing the inorganic lead halide perovskite nanocrystal colloidal solution with chelating agent ligand powder, stirring for a certain time, filtering, centrifuging, and re-dispersing to obtain a passivated nanocrystal solution. The luminous efficiency and the stability of the inorganic perovskite nanocrystal passivated by the chelating agent ligand are greatly improved, and the inorganic perovskite nanocrystal can efficiently emit light for more than one month in an ethanol solvent; the stability of the prepared nanocrystalline material in a polar environment is enhanced, the external quantum efficiency and brightness are obviously improved after the nanocrystalline material is prepared into a light-e
