Abstract
This disclosure pertains to the field of nanotechnology. The disclosure provides methods of preparing nanostructures with fluoride passivation. The disclosure also provides methods of preparing nanostructures with fluoride and amine passivation. The nanostructures have high quantum yield, narrow emission peak width, tunable emission wavelength, and colloidal stability. Also provided are nanostructures prepared using the methods. And, nanostructure films and molded articles comprising the nanostructures are also provided.
Claims17
