| description | The invention relates to the technical field of preparation of quantum dots, in particular to a preparation method of deep blue light efficient narrow-band perovskite quantum dots. The invention provides a preparation method of deep blue light efficient narrow-band perovskite quantum dots, which comprises the following steps: mixing alkyl trimethyl ammonium bromide and N, N-dimethylformamide for the first time to obtain a soft template precursor solution; cesium halide, lead halide, amino hydrobromide and N, N-dimethylformamide are mixed for the second time, and a perovskite quantum dot precursor solution is obtained; and mixing the soft template precursor solution, the perovskite quantum dot precursor solution and an anti-solvent, carrying out a precipitation reaction, and carrying out centrifugal purification and separation to obtain the dark blue light efficient narrow-band perovskite quantum dot. The perovskite quantum dot prepared by the preparation method shows ultrahigh color purity, and has extremely |
