Synthesis and characterization of Sb2Te3 nanowires

Sb2Te3 nanowires were synthesized by hydrothermal treatment at 450 K and pH 11, and their microstructure analysed by X-ray diffraction, transmission electron microscopy (TEM), and differential scanning calorimetry (DSC). Sb2Te3 nanowires growing from a nanoplate were observed by TEM, which revealed them to grow along the (0 1 5) direction. DSC showed that the transformation point between crystalline and molten state of the Sb2Te3 nanowires is 727.5K. A possible mechanism for the formation of the Sb2Te3 nanowire structures is discussed.
