Method of manufacturing quantum dot using metal oxide nanoparticle with high specific surface area and quantum dot manufactured by the method

The present invention relates to the thermal stability and the excellent light scattering method using a quantum dot nano-metal oxide. To this end, (a) zinc (Zn), cadmium (Cd), mercury (Hg), indium (In), copper (Cu), mixing by selecting the at least one or more of the added ethylene-based hydrocarbon organic solvent to the fatty acids by synthesizing a cationic precursor; (B) alkyl phosphine series, selenium to any one of the series group selected from the group consisting of alkyl oxide phosphine series, trialkylphosphine series (Se), sulfur (S), phosphorus (P), at least one from Tel runyum (Te) mixing to synthesize the anionic precursor or more; And (c) a quantum dot production method and a production, comprising the (a) mixing the anionic precursor synthesized in the cation precursor and the step (b) prepared in step at a predetermined rate, and synthesizing the quantum dots is reacted at a given temperature It provides a quantum dot according to the method.
