Synthesis and optical property of Sb2Se3 nanowires

A simple solvothermal approach has been developed for the fabrication of large-scale single-crystalline Sb2Se3 nanowires. The average diameter of the nanowires is about 100 nm, and the length is range from 1 to 2 microm. X-ray diffraction, X-ray photoelectron spectroscopy, scanning electron microscopy, transmission electron microscopy, and electron diffraction were used to characterize the samples. The optical property of Sb2Se3 nanowires was characterized by solid-state UV-visible absorption spectroscopy, and the band gap (E(g)) derived to be 1.26 eV.
