Size control and quantum confinement in Cu2ZnSnS4 nanocrystals

Author affiliations

Abstract

Starting with metal dithiocarbamate complexes, we synthesize colloidal Cu2ZnSnS4 (CZTS) nanocrystals with diameters ranging from 2 to 7 nm. Structural and Raman scattering data confirm that CZTS is obtained rather than other possible material phases. The optical absorption spectra of nanocrystals with diameters less than 3 nm show a shift to higher energy due to quantum confinement.
