摘要：
The analysis of the vibrational properties of mechanochemically synthesized stannite Cu2FeSnS4 nano crystals has been performed. X-ray diffraction (XRD) and Raman spectroscopy are techniques used to characterize the crystal structure and compositional purity of stannite Cu2FeSnS4 nanoparticles. The detailed analysis of the experimental spectra has allowed us to determine the frequency and symmetry assignment of the main and weaker peaks. The milling time influence on synthesis stannite Cu2FeSnS4 from elemental precursors Cu, Fe, Sn and S is observed. Among the peaks that are characteristic for the stannite Cu2FeSnS4, we registered the modes of binary phases of FeS and SnS. The total disappearance of the binary phases of FeS and SnS is observed when the milling time is longer than 90 min. (C) 2017 Elsevier B.V. All rights reserved.
