Abstract

A simple L-cystine-assisted synthetic route has been successfully developed to prepare Cu 3 SbS 3 nanorods under solvothermal conditions. In this synthetic system, we used CuCl 2 as the copper source, SbCl 3 as the antimony source, and L-cystine as both sulfur source and complexing reagent. The obtained Cu 3 SbS 3 nanorods were characterized by XRD, XPS, FESEM and TEM (HRTEM). The results showed that the Cu 3 SbS 3 nanorods were 100–150 nm in width and several micrometers in length. A possible formation mechanism for Cu 3 SbS 3 nanorods was also discussed. The proposed solvothermal method using L-cystine as the sulfur source provides an alternative approach to prepare other ternary semiconductor nanomaterials.

Abstract

Abstract: Flower-like Cu3BiS3 nanorods were successfully synthesized via a facile biomolecule-assisted solvothermal method at 200°C for 16h, employing CuCl2·2H2O, Bi(NO)3·5H2O and l-cystine as reactants. The morphology, structure, and composition of the obtained products were confirmed by X-ray powder diffraction (XRD), energy dispersion spectroscopy (EDS), field-emission scanning electron microscopy (FESEM), X-ray photoelectron spectroscopy (XPS), and transmission electronic microscopy (TEM). Results indicated that the flower-like Cu3BiS3 nanostructure consists of many nanorods with an average diameter about 150nm. Moreover, the optical properties of flower-like Cu3BiS3 nanorods were investigated by Raman and photoluminescence spectroscopy. The PL spectrum showed that a strong UV emission peak located at around 356nm and a weak and shoulder emission situated at 379nm. Raman spectrum exhibited four distinct vibrational peaks at about 116, 153, 355 and 459cm−1. [Copyright &y& Elsevier]
