Abstract
The photon-sensing abilities of SnO 2 nanowires have been investigated before and after surface fluorination by microwave plasma-enhanced chemical vapor deposition. The electrical conductance and photon-sensing abilities of SnO 2 nanowires were remarkably improved by an effective doping of fluorine into the surface of the nanowires. These results demonstrated that the fluorinated SnO 2 nanowires have potential applications as UV photodetectors with high photon-sensing properties. © 2009 The Electrochemical Society.
