Product Description

Bismuth (metal) Granular 

The large-area arrays of one-dimensional (1D) nano wires and nano flowers of bismuth oxide (Bi2O3) were synthesized by the oxidative metal vapour phase deposition technique with controlled flow of oxygen and constant working pressures. Surface morphology analysis showed that the as-synthesized product at 10 Torr consisted of 1D nano wires with diameters about 13-42 nm and lengths up to several tens of micrometres. The other working pressure of 30 Torr accounted for the formation of nano flowers with a petal-like structure. Elemental analysis confirms the presence of only the elements Bi and O. The crystalline nature of the 1D nano structure 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 monoclinic α-Bi2O3 and tetragonal β-Bi2O3. Raman signals of the synthesized nano structures are identified and assigned to various phonon vibration modes of Bi and Bi2O3. The photo luminescence (PL) spectrum shows a visible broadband emission in the wavelength range, 500-800 nm.
