| titleOfInvention | A kind of sieving method of quantum dot and quantum dot light-emitting diode |
| abstract | The invention discloses a method for sieving quantum dots and a quantum dot light-emitting diode, wherein the sieving method comprises the steps of: dispersing the initial quantum dots with organic ligands connected on the surface in a first solvent to obtain the initial quantum dots solution; gradually add an insoluble solvent to the initial quantum dot solution and mix, so that the initial quantum dots are gradually precipitated according to the order of particle size from large to small, and the precipitates are collected in chronological order to obtain the sieved quantum dots. At this point, the insoluble solvent is miscible with the first solvent, and is immiscible with the organic ligand. The size deviation of the quantum dots separated by the present invention can be controlled within 5% at least, so as to obtain quantum dot materials with uniform size; using the quantum dots with uniform size as the material of the quantum dot light-emitting layer can effectively improve the photoelectricity of the quantum dot light-emitting diode. performance. |
