| titleOfInvention | ABX3Preparation method of type all-inorganic perovskite nanocrystalline |
| abstract | The invention discloses an ABX 3 A preparation method of type all-inorganic perovskite nanocrystalline. The preparation process has the advantages of low solvent consumption and low unit price of raw materials (such as replacing expensive PbX by cheap lead acetate and the like) 2 Raw materials), the preparation process has low requirements on environment, a glove box is not required, the operation procedure is simple, and the cost of the raw materials and instruments is greatly reduced. The target product can be synthesized by the nanocrystalline at a wide temperature range of 0-300 ℃ in the preparation process, the morphology, phase, size and luminescence property of the nanocrystalline can be controlled by changing the raw material proportion, solvent proportion, reaction temperature and/or reaction time, for example, perovskite nanowires can be prepared at the temperature of more than or equal to 0 ℃ and less than 90 ℃, and perovskite quantum dots can be prepared at the temperature of 90-300 ℃. The nanocrystal has good stability and high fluorescence quantum yield (26-80%), can realize luminescence in a full visible spectrum (400-700nm), and the preparation method has the advantages of simple process, short time consumption, low cost, easy amplification and synthesis, and is suitable for industrial large-scale preparation. |
