Preparation of large scale and highly ordered vanadium pentoxide (V2O5) nanowire arrays towards high performance photodetectors

Abstract

Large scale and highly ordered vanadium pentoxide (V2O5) nanowire arrays were successfully prepared. The nanowires were arranged parallel in the same direction and formed into a uniform and compact structure by using the improved self-assembly method. The V2O5 nanowire arrays were obtained from the in situ high temperature treatment of VO2(A) nanowire arrays. The as prepared V2O5 nanowire arrays show an excellent light response under visible light irradiation at room temperature. Experimentally, when the incident light intensity is 105 mW cm−2, the arrays exhibit a high responsivity of 160.3 mA W−1, a high detectivity of 6.5 × 108 Jones and a fast response time. These results pave the way for an effective approach to fabricate large-scale ordered semiconductor nanowire arrays and promising photoelectric detectors.
