Abstract
Disclosed are films comprising Ag In, Ga, and S (AIGS) nanostructures and at least one ligand bound to the nanostructures. In some embodiment, the AIGS nanostructures have a photon conversion efficiency of greater than 32% and a peak wavelength emission of 480-545 nm when excited using a blue light source with a wavelength of about 450 nm.
