Optimization, yield studies and morphology of WO3 nano-wires synthesized by laser pyrolysis in C2H2 and O2 ambients—validation of a new growth mechanism

Author: Mwakikunga, Bonex W ; Forbes, A ; Sideras-Haddad, E ; Arendse, C Date: Oct 2008 Laser 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
Raman spectroscopy of WO3 nano-wires and thermo-chromism study of VO2 belts produced by ultrasonic spray and laser pyrolysis techniques

Author: Mwakikunga, Bonex W ; Sideras-Haddad, E ; Forbes, A ; Arendse, C Date: 2008 Novel 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
