Claim 17:
18. The process of any of claim 15, wherein step (I) comprises:
(Ia) providing a first dispersion system at a first temperature, the first dispersion system comprising a salt of a long-chain organic acid and M1, optionally a salt of the long-chain organic acid and M2, optionally a salt of the long-chain organic acid and M3, a long-chain hydrocarbon solvent, optionally a salt of a second organic acid and M1, optionally a salt of a third organic acid and M2, optionally a salt of a fourth organic acid and M3, optionally sulfur or an organic sulfur compound soluble in the long-chain hydrocarbon solvent, and optionally an organic phosphorous compound soluble in the long-chain hydrocarbon solvent; and
(Ib) heating the first dispersion system to a second temperature higher than the first temperature but no higher than the boiling point of the long-chain hydrocarbon solvent, where at least a portion of the salt(s) of the long-chain organic acid and at least a portion of the salt(s) of the second organic acid, if present, to form a second dispersion system comprising nanoparticles dispersed in the long-chain hydrocarbon solvent, and the nanoparticles comprise kernels, and the kernels comprise M1, optionally M2, optionally M3, oxygen, optionally sulfur, and optionally phosphorus;
(Ic) separating the nanoparticles from the second dispersion system; and
(Id) dispersing the nanoparticles separated in (Ic) in the liquid medium to form the nanoparticle dispersion.
