| titleOfInvention | A kind of preparation method of high stability perovskite quantum dots |
| abstract | The invention provides a method for synthesizing perovskite quantum dots with high stability and high quantum efficiency. The perovskite quantum dot material of the present invention makes the perovskite quantum dots react between the montmorillonite sheets through the adsorption between the montmorillonite and cations, and the perovskite nanoparticles pass through the sheets. The structure is separated, which can effectively reduce the free exchange of ions between perovskite quantum dots, and at the same time, the lamellar structure has a high resistance to water vapor and oxygen, which greatly improves the stability of quantum dots. The specific steps are: a. Mix CsX with water and ethanol, and stir well until completely dissolved; b. Add lamellar montmorillonite to the solution in step a, Cs+ cations are adsorbed between the montmorillonite lamellae; the reaction is completed Then, centrifugally wash 3 times, and disperse in octadecene after vacuum drying; c. Mix and stir the lead source, organic long-chain acid, organic long-chain amine and solvent to form a transparent liquid; d. Disperse in step b The liquid is rapidly injected into the clear liquid of step c. |
