Abstract

High quality single crystalline VO2(A) nanowires were synthesized by a facile hydrothermal method using oxalic acid as reducing agent and polyethylene glycol 6000 as surfactant. It was found that polyethylene glycol 6000 can effectively accelerate the transformation from V2O5 precursor to VO2(B), and there is no intermediate phase V3O7?H2O formed. Thus less time and lower temperature were needed in our hydrothermal method. The investigation of growth mechanism indicates an oriented attachment growth process in the hydrothermal system. In addition, the temperature-dependent optical switching properties have been studied. The results show that VO2(A) nanowires exhibit distinct temperature-dependent optical switching properties, which can be potentially explored for optical switching devices.
