Fabrication method of InP based quantum dot by using aminophosphine type P precursor and core size-sorting procedure
A method for fabricating quantum dots according to the present disclosure includes (a) synthesizing InP cores based on an aminophosphine type phosphorus (P) precursor, (b) size-sorting the InP cores, and (c) forming at least two shells on the size-sorted InP cores. In this instance, the size-sorting includes precipitating the InP cores with an addition of a dispersive solvent and a nondispersive solvent to the InP cores and separating the InP cores using a centrifugal separator, wherein the InP cores are separated in a descending order by size by performing iteration with a gradual increase in an amount of the nondispersive solvent.
