1. A method of manufacturing quantum dots, the method comprising:
placing nickel powder having a certain particle size, a precursor material, and an organic solvent into a container;
maintaining a pressure in the container at a certain value;
synthesizing quantum dots by stirring the nickel powder, the precursor material, and the organic solvent in the container;
heating the synthesized quantum dots to at least a first temperature for at least a first time under an argon atmosphere; and
heat-treating the synthesized quantum dots at the at least the first temperature for a second time greater than the first time, under the argon atmosphere.
