Abstract

Orthorhombic, - phase, Sb 2O 4 nanowire was fabricated by heating Sb 2S 3 powder. At 500C, the grown product had the morphology of nanowire with an average diameter of ∼100 nm. At 600C, it became a continuous film with nodular morphology. The structure, crystallinity, and phase-purity of the nanowire were investigated using X-ray diffraction spectroscopy, high-resolution transmission electron microscopy, and selected-area electron diffraction. These measurements, combined with those obtained using X-ray photoelectron, Raman, and photoluminescence spectroscopy, indicate that the as-grown nanowires were crystalline with an orthorhombic -Sb 2O 4 structure. This study confirmed that thermal evaporation of the Sb 2S 3 precursor is a viable and simple approach to produce nanostructured -Sb 2O 4 materials selectively.
