Abstract
In this work, ultrahigh-aspect-ratio Sb2Se3 nanowires have been controllably prepared by a mild hydrothermal treatment. X-ray diffraction, X-ray photoelectron spectra, scanning electron microscopy, transmission electron microscopy, high-resolution transmission electron microscopy, and selected area electron diffraction were used to characterize the as-synthesized samples. The result revealed that the as-synthesized products were wire-like with diameter ranging from 20 to 30 nm and length of 30 μm. Meanwhile, various experimental parameters such as concentration of precursors, influence of ethylenediamine, reaction time and the formation of mechanism were discussed and properties of photoconductive of Sb2Se3 were also investigated in detail. In addition, to the best of our knowledge, there have been no any reports on the one-pot synthesis of Sb2Se3 nanomaterials under the benzyl alcohol system.
