Author:Govender, M; Mwakikunga, Bonex W; Machatine, AGJ; Kunert, HWDate:Feb 2014Laser pyrolysis was chosen to synthesize tungsten trioxide starting with tungsten ethoxide precursor. The film was found to have a thickness that varied from 205 nm to 1 µm. X-ray diffraction and Raman spectroscopy confirmed the presence of ...Read more

Author:Mwakikunga, Bonex W; Malwela, T; Hillie, T; Ndlovu, GDate:Oct 2011Traditional gas sensors involve heating the sensor material for gas selectivity. New gas approaches require activation by a broadband UV light source. The authors propose to employ a tuneable UV source in which this source is tuned for its ...Read more
