| titleOfInvention | A kind of perovskite quantum dots and metal organic framework composite light-emitting material and its preparation method and application |
| abstract | The invention discloses a perovskite quantum dot and metal-organic framework composite light-emitting material, a preparation method and application thereof. The method comprises the following steps: mixing lead halide, cesium halide, imidazole ligand and central metal atom compound, grinding After 5 to 50 minutes, the perovskite quantum dot and the metal organic framework composite light-emitting material is obtained; the central metal atom compound is one or more of zinc oxide, cobalt hydroxide or zinc acetate. The invention synthesizes the perovskite quantum dots and the metal-organic framework composite light-emitting material in one step through mechanical grinding, and solves the problem of reducing the size of the perovskite by using a surfactant in the prior art. The method of the invention is green and environmentally friendly, and while improving the stability of the perovskite quantum dots, the optical properties of the composite material are also improved. |
