摘要：

A new composite thin film of vanadium dioxide (VO2) nanowire/carbon nanotube (CNT) has been prepared by a hydrothermal method. The VO2 nanowires were covered on the whole upper surfaces of CNT and combined very well with the CNT film. XRD and Raman spectra revealed that the as-synthesized composite film had good crystallization. The film presented favorable photoelectric response at the room temperature due to the excellent thermal conductivity of CNT film and their large effective illumination area. The obtained results revealed that photocurrent showed a strong dependence on the bias voltage and incident infrared light intensity. Furthermore, the infrared photoelectric response exhibited an obvious enhancement with decreasing the thickness of the VO2 films. The responsivity (R (lambda) ) can reach up to 17.83 mA/W for the film thickness of 25 mu m, and the rise and decay time are about 0.84 and 0.56 s, respectively.
