1. A method of producing nanoparticles comprising.(a) mixing a first precursor and at least one coordinating solvent to form a first mixture;

  • (b) exposing the first mixture to a reaction promoter, different from the coordinating solvent, selected from the group consisting of oxygen and a reducing agent, to thereby reduce the first precursor'"'"'s valency;

    (c) heading the first mixture to a temperature that is sufficiently high to of form nanoparticles when a second precursor is added;

    (d) introducing a second precursor into the first mixture after the first precursor'"'"'s valency has been reduced to form a second mixture thereby resulting in the formation of a plurality of nanoparticles; and

    (e) cooling the second mixture to stop further growth of the nanoparticles.
