Author:Mwakikunga, Bonex W; Forbes, A; Sideras-Haddad, E; Arendse, CDate:Oct 2008Laser pyrolysis has been used to synthesize WO3 nanostructures. Spherical nano-particles were obtained when acetylene was used to carry the precursor droplet, whereas thin films were obtained at high flow-rates of oxygen carrier gas. In both ...Read more
Author:Mwakikunga, Bonex W; Sideras-Haddad, E; Forbes, A; Arendse, CDate:2008Novel optical and electrical properties of newly synthesized nano-wires of monoclinic WO3 and nano-belts of rutile VO2 have been investigated by Raman spectroscopy and thermochromism studies respectively. Phonon confinement is observed in the ...Read more
