摘要:
This disclosure pertains to the field of nanotechnology. The disclosure provides nanostructure compositions comprising (a) at least one population of nanostructures; (b) at least one metal halide bound to the surface of the nanostructures; and (c) at least one metal carboxylate bound to the surface of the nanostructures. The nanostructure compositions have high quantum yield, narrow emission peak width, tunable emission wavelength, and colloidal stability. Also provided are methods of preparing the nanostructure compositions. And, nanostructure films and molded articles comprising the nanostructure compositions are also provided.
