Claim Text:
1. A nanoparticle prepared by a process comprising: effecting conversion of a nanoparticle precursor composition to a core semiconductor material, the precursor composition comprising a first precursor species containing a first ion to be incorporated into the core semiconductor material and a separate second precursor species containing a second ion to be incorporated into the core semiconductor material, wherein the conversion is effected in the presence of a molecular cluster compound that contains at least one element of the nanoparticle not present in either the first precursor species or the second precursor species, the conversion is effected under conditions permitting seeding and growth of the nanoparticles and the ratio of the number of moles of the molecular cluster compound to the total number of moles of the first and second precursor species is between 0.0035:1 and 0.0045:1.
