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...http://www.google.com.au/patents/US7267810?utm_source=gb-gplus-sharePatent US7267810 - Method of synthesizing colloidal nanocrystals
