Abstract
A method of making nanocrystals involves adding a chalocogen source to a hot solution of a metal-containing non-organometallic compound, such as CdO, in a first ligand solvent, such as TOP, and preferably subsequently cooling the resulting mixture to a lower temperature to grow the nanocrystals at said lower temperature. The method can involve either one ligand or two-ligand systems.
