“Green” Aqueous Synthesis and Advanced Spectral Characterization of Size-Selected Cu(2)ZnSnS(4) Nanocrystal Inks

Structure, composition, and optical properties of colloidal mercaptoacetate-stabilized Cu(2)ZnSnS(4) (CZTS) nanocrystal inks produced by a “green” method directly in aqueous solutions were characterized. A size-selective precipitation procedure using 2-propanol as a non-solvent allows separating a s...

description Structure, composition, and optical properties of colloidal mercaptoacetate-stabilized Cu(2)ZnSnS(4) (CZTS) nanocrystal inks produced by a “green” method directly in aqueous solutions were characterized. A size-selective precipitation procedure using 2-propanol as a non-solvent allows separating a series of fractions of CZTS nanocrystals with an average size (bandgap) varying from 3 nm (1.72 eV) to 2 nm (2.04 eV). The size-selected CZTS nanocrystals revealed also phonon confinement, with the main phonon mode frequency varying by about 4 cm(−1) between 2 nm and 3 nm NCs.
