Abstract

One-dimensional (1D) SnO2 nanowires were synthesized from SnO powder by heat treatment of SnO powder under Ar gas flow at atmospheric pressure, with the next annealing on the air at 1000 °C. The morphology and microstructure of the single crystalline SnO2 nanowires are characterized by means of the X-ray diffraction (XRD) and scanning electron microscopy (SEM). The band gaps of the products are ~(3.42–3.78 eV) determined from UV/visible absorption spectral results. The SnO2 nanowires show stable photoluminescence (PL) with one emission peak centred at around ~2 eV.
