Abstract
A method for forming inorganic structures includes (a) transferring nanocrystals to a polar protic solvent using at least one chalcogenide precursor to produce a negatively-charged chalcogen-rich nanocrystal surface, (b) removing excess anions of the chalcogenide precursor, (c) introducing a metal salt to bind a divalent metal cation to the negatively-charged chalcogen-rich nanocrystal surface to regenerate a positively-charged metal-rich nanocrystal surface, and (d) removing excess divalent metal cations of the metal acetate salt.
