METHOD OF MANUFACTURING CONTINUOUS FLOW OF QUANTUM DOTS AND APPARATUS FOR MANUFACTURING QUANTUM DOT CONTINUOUS FLOW

摘要

The purpose of the present invention is to provide a method of manufacturing a continuous flow of quantum dots, and an apparatus for manufacturing a quantum dot manufacturing continuous flow, the method and apparatus which can form ligands in the quantum dots by the continuous process. The method of manufacturing a continuous flow of quantum dots comprises the steps of: passing a core precursor solution through a first heating unit provided in a first pipe, and heating the core precursor solution by the first heating unit to prepare a core-containing solution; transferring the core-containing solution and a first shell precursor solution including a first ligand to a quantum dot-forming solution preparing mixer through the first and second pipes, respectively, and mixing the core-containing solution and the first shell precursor solution to prepare a first solution; passing the first solution through a second heating unit provided in a third pipe, heating the first solution by the second heating unit, thereby growing a first shell to prepare a second solution containing particles having a structure in which a core, the first shell surrounding the core, and the first ligand surrounding the first shell are formed; transferring the second solution and a second ligand precursor solution to a third solution preparing mixer through the third and fourth pipes, and mixing the second solution and the second ligand precursor solution to prepare a third solution; and passing the third solution through a third heating unit provided in a fifth pipe, heating the third solution by the third heating unit, making particles having a structure, in which a core, the first shell surrounding the core, and the first ligand surrounding the first shell are formed, react with the second ligand precursor solution, thereby exchanging the first ligand surrounding the first shell with a second ligand of the second ligand precursor solution to form quantum dots having a structure in which a core, the first shell surrounding the core, and the second ligand surrounding the first shell are formed. Further, the present invention provides the apparatus for manufacturing a quantum dot manufacturing continuous flow by the method.;COPYRIGHT KIPO 2018
