How it works

A method of synthesizing colloidal semiconductor nanocrystals involves contacting a source of at least one semiconductor cation element with a source of at least one Group 15 or 16 element in the presence of a ligand forming compound containing a carboxylic acid moiety. The cation element is preferably bonded to deficient carbon acids. The method produces novel ensembles of colloidal semiconductor nanocrystals that have narrow linewidth absorption and bandgap photoluminescence spectra.
