Colloidal Synthesis and Characterization of Nanowires of Triclinic Cu3SnS4

Abstract

In this paper we report the colloidal synthesis and characterization of triclinic nanowires of Cu3SnS4. The XRD pattern of the as-prepared sample matches well with JCPDS No. 33-0501. Triclinic crystals of average crystallite size of about 3.7 nm were formed. The absorption spectrum consists of two SPR peaks which are characteristic of nanowires, corresponding to the axial and longitudinal vibrations of electrons on its surface. The bandgap of Cu3SnS4 nanowire is found to be 1.66 eV and so it can find application in the absorber layer of solar cells.
