Synthesis and characterization of orthorhombic Sb ₂O ₄ nanowire prepared by heating Sb ₂S ₃ powder

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.
