摘要

A method of manufacturing a quantum dot-oxide composite in which fluorescence stability under deteriorated conditions is improved without reducing the quantum efficiency (QY), and an on-chip package quantum dot-LED manufacturing method using the same are provided. The method for producing a quantum dot-oxide composite according to the present invention comprises the steps of: preparing a quantum dot dispersion in which quantum dots are dispersed in a solvent; Adding an oxide precursor to the quantum dot dispersion to prepare a mixed solution; And placing the mixed solution in a thermo-hygrostat without adding a catalyst or water to the mixed solution to surround the quantum dots with an oxide derived from the oxide precursor.
