Abstract
The large-area arrays of one-dimensional (1D) nanowires and nanoflowers of bismuth oxide(Bi2O3) were synthesized by the oxidative metal vapour phase deposition technique withcontrolled flow of oxygen and constant working pressures. Surface morphology analysisshowed that the as-synthesized product at 10 Torr consisted of 1D nanowires with diametersabout 13–42 nm and lengths up to several tens of micrometres. The other working pressureof 30 Torr accounted for the formation of nanoflowers with a petal-like structure. Elementalanalysis confirms the presence of only the elements Bi and O. The crystalline nature of the1D nanostructure is revealed by high resolution transmission electron microscopy(HRTEM) and selected-area electron diffraction (SAED) studies. X-ray diffraction(XRD) analysis indicates the formation of a two-phase system with monoclinicα-Bi2O3 andtetragonal β-Bi2O3. Raman signals of the synthesized nanostructures are identifiedand assigned to various phonon vibration modes of Bi andBi2O3. The photoluminescence (PL) spectrum shows a visible broadband emission in thewavelength range, 500–800 nm.
