Abstract: Disclosed herein is a method of forming a spherical InP quantum dot, including: providing a compound containing indium (In); dissolving the compound in alcohol to form a solution; and introducing a compound containing phosphorus (P) into the solution. The method is advantageous because a spherical InP quantum dot can be formed, the method is environment-friendly because alcohol is used as a solvent, because InP quantum dots can be produced in large quantities because the InP quantum dots can be formed while putting all reactants into a reactor and slowly heating the reactants, and because the desired InP quantum dots can be easily recovered by decreasing the temperature of a reactor or by performing centrifugal separation at low speed.
