| titleOfInvention | Preparation method and quantum dot device of perovskite quantum dots coated with zinc sulfide or zinc selenide |
| abstract | The invention provides a preparation method of a zinc sulfide or zinc selenide-coated perovskite quantum dot and a quantum dot device containing the same. The preparation method includes: S1, subjecting zinc halide, aliphatic amine and acid to a halogen precursor preparation reaction to obtain a first mixed solution containing ammonium halide and zinc salt; S2, preparing lead carboxylate and cesium carboxylate, the first VI group The precursor and the organic solvent are reacted to obtain a second mixed solution; S3, the first mixed solution and the second mixed solution are mixed and reacted to obtain a perovskite containing a thin layer of zinc sulfide or a thin layer of zinc selenide at least partially coated The third mixed solution of quantum dots; S4, the zinc carboxylate precursor and the second group VI precursor are sequentially added to the third mixed solution to react to obtain zinc sulfide or zinc selenide-coated perovskite quantum dots. Therefore, the purpose of coating zinc sulfide or zinc selenide shell layer on the surface of all-inorganic perovskite quantum dots is achieved, the reaction process is controllable, the repeatability is good, and it has good stability in polar solvents. |
