Abstract
Methods of preparing a dispersion of colloidal nanocrystals (NCs) for use as NC thin films are disclosed. A dispersion of NCs capped with ligands may be mixed with a solution containing chalcogenocyanate (xCN)-based ligands. The mixture may be separated into a supernatant and a flocculate. The flocculate may be dispersed with a solvent to form a subsequent dispersion of NCs capped with xCN-based ligands.
