Facile synthesis of ultra-long Cu2CdSnS4 nanowires with wurtzite-derived structure

A facile and inexpensive method was developed to synthesize high quality and ultra-long Cu2CdSnS4 (CCTS) nanowires. X-ray diffraction (XRD) and Raman spectra studies indicated that wurtzite structured CCTS was formed. The nanowires had diameters of 80-100 nm and lengths of up to several micrometers. The bandgap of CCTS nanowires was about 1.42 eV determined by UV-vis-NIR absorption spectrum. The photoresponses of CCTS nanowire thin films indicated that they were promising for use in photovoltaic applications. (C) 2014 Elsevier B.V. All rights reserved.
