Abstract

The present invention relates to a method for manufacturing quantum dots and quantum dots manufactured thereby, the method for manufacturing quantum dots comprising the steps: heating a first solution containing a first zinc precursor, a first carboxylic acid-based compound, and a first organic solvent; adding a first mixture of a first selenium (Se) precursor and a telenium (Te) precursor to a second organic solvent to form a second solution; mixing the heated first solution and the second solution to form a ZnSeTe core; and forming at least one layered shell on the ZnSeTe core, wherein the difference in polarity index of the second organic solvent from the first organic solvent is in the range of 0-0.4.
