| titleOfInvention | A kind of synthetic method of non-lead double perovskite nanocrystals |
| abstract | The invention discloses a method for synthesizing lead-free double perovskite nanocrystals. DMF is used as a solvent for dissolving cesium iodide, sodium iodide and bismuth iodide reactants to obtain a precursor solution; isopropanol is used as an anti-solvent. After adding the precursor solution to the anti-solvent, and centrifuging the supernatant to obtain a nanocrystalline material with a chemical formula of Cs 2 NaBiI 6 and a cubic crystal form and an exciton peak of 509 nm. Cs 2 NaBiI 6 perovskite nanocrystals are synthesized for the first time in the present invention. By selecting elements with high abundance and low toxicity in the earth's crust, and adopting the principle of the LARP method with relatively simple process and low experimental environment requirements, the precursor is synthesized. The bulk solution is injected into a mutually miscible anti-solvent, and the precursor substance precipitates into a crystal. The materials used in the synthesis of the present invention are rich in resources, low in cost, and can be mass-produced. The obtained nanocrystalline light-emitting material has a perovskite structure and an adjustable light-emitting range, making it a low-cost quantum quantum material with development potential. Point luminous material. |
