Abstract
A semiconductor nanocrystal composition comprising a Group V to VI semiconductor material and a method of making same. The method includes synthesizing a semiconductor nanocrystal core, where the synthesizing includes dissolving a Group V to VI anion gas in a first solvent to produce a Group V to VI anion precursor, preparing a cation precursor, and reacting the Group V to VI anion precursor with the cation precursor in the presence of a second solvent. The reacting may occur in a high pressure vessel.
