Abstract

We report the synthesis of one-dimensional (1D)Bi2O3 nanohooks by the oxidative metal vapor phase deposition technique. Surface morphologyobservations confirm the formation of 1D nanohooks with nanoparticles at theirtips. Structural analysis by x-ray diffraction (XRD) and transmission electronmicroscopy (TEM) reveals the crystalline nature of the 1D nanostructure.Elemental analysis confirms that the 1D nanohooks consist of only elements Biand O. The XRD study suggests that the synthesized product is of two phases(α- and β-Bi2O3) withmonoclinic and tetragonal crystal structures respectively. The phonon vibration modes correspondingto Bi2O3 are determined by Raman scattering. A broadband visible photoluminescence (PL) isobserved in the wavelength region 500–900 nm, also indicating the extension ofluminescence into the near-infrared region. The existence of broadband visible emission canbe attributed to the existence of defect/impurity states induced by oxygen vacancies.
