Abstract

We report on the time dependent growth of vanadium pentoxide (V ₂O₅) nanowires in V₂O₅ sols prepared from ammonium (meta)-vanadate in the presence of an acidic ion exchanger at different temperatures. V₂O₅ nanowires were adsorbed on SiO₂/Si substrate pretreated with 3-aminopropyltriethoxysilane (3-APS) and the structural evolution at 24°C was investigated by atomic force microscope (AFM) and scanning tunneling microscope (STM). Optical absorption and current-voltage measurements confirmed the gradual growth of V₂O₅ nanowires with time. At the higher temperatures of the sol solution, the elongation rate of the V₂O₅ nanowires was enhanced, indicating the endothermic growth process.
