In pondering of new promising transparent conductors to replace the cost rising tin-doped indium oxide (ITO), metal nanowires have been widely concerned. Herein, we demonstrate an approach for successful synthesis long and fine Cu (NWs) through a novel catalytic scheme involving nickel ions. Such NWs in high aspect ratio (diameter 16.2 ± 2 nm length up 40 μm) provide distance electron transport and, meanwhile, large space light transmission. Transparent electrodes fabricated using NW ink...
