Abstract
Disclosed are nanostructures comprising Ag, In, Ga, and S and a shell comprising Ag, Ga and S, wherein the nanostructures have a peak wavelength emission of 480-545 nm and wherein at least about 80% of the emission is band-edge emission. Also disclosed are methods of making the nanostructures.
Claims7
A method of making nanostructures, the method comprising:
- (a) reacting Ga (acetylacetonate) 3, InCl3, and a ligand at a temperature sufficient to give an In—Ga reagent;
- (b) reacting the In—Ga reagent with Ag2S nanostructures at a temperature sufficient to make AIGS nanostructures;
- (c) reacting the AIGS nanostructures with an oxygen-free Ga salt in a solvent containing a ligand at a temperature sufficient to form AIGS/AGS core-shell nanostructures.
