Hydrothermal synthesis of Sb2S3 nanorod ordered arrays

Using Sb (S2CNEt2)(3) as a single-source precursor, ordered arrays of Sb2S3 column-like and needle-like nanorods with various sizes have been synthesized via a hydrothermal treatment by adjusting the reaction conditions such as time, temperature and surfactant. X-ray powder diffraction (XRD), energy-dispersive spectroscopy (EDS) and selected-area electron diffraction (SAED) results demonstrate that the nanorods are composed of pure orthorhombic Sb2S3 single-crystal. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) show that the Sb,S, nanorods are highly ordered with controllable diameter and length in ranges from 60 similar to 300 nm and 2 similar to 5 mu m, respectively. On the basis of the experimental results, the influences of the reaction conditions on the formation of the Sb2S3 nanorod arrays are discussed.
