Abstract
Methods for precise and predictable modification of previously synthesized nanocrystals. The methods rely on the solubility behavior of crystalline materials to provide for controlled reversal of the nanocrystal growth process (i.e., dissolution). A method for post-synthesis modification of colloidal nanocrystals includes (1) providing a first nanocrystal having a first size and a first shape, (2) forming a reaction mixture that includes the nanocrystal, at least one ligand capable of binding to at least one component of the nanocrystal, at least one solvent, and an inert gas atmosphere, and (3) modifying the size and/or shape of the nanocrystal in the reaction mixture for a period of time at a temperature in a range from about 100 0C to about 240 0C so as to produce at least a second nanocrystal having a second size and/or a second shape.
