The electrical conductivity of as-synthesized ITO NW was similar to 115.9 S/cm at room temperature. Photocurrent generation devices were prepared by self-assembling di(3-aminopropyl)viologen and Ru(2,2'-bipyridine-4,4'-dicarboxylic acid)(2)(NCS)(2) on the surface of ITO NWs. The maximum photocurrent density of the device with an ITO NW electrode under illumination of 100 mW/cm(2) was 11.05 mu A/cm(2), which is about three orders of magnitude larger than that of the device with a bare ITO thin film electrode. The high photocurrent density could be attributed to the large surface area, high crystallinity, and electrical conductivity of the ITO NW electrode. (C) 2014 Elsevier Ltd and Techna Group S.r.l.
