title: Single-crystalline Bi(2)S(3) nanowire network film and its optical switches.
abstract: A single-crystalline bismuth sulfide (Bi(2)S(3)) nanowire network film at a centimeter scale is fabricated by the facile hydrothermal method. The Bi(2)S(3) film is easily tape-transferred onto a soft plastic substrate, and is further used to fabricate optical switches by screen-printing an Ag electrode array on its top. Our studies demonstrate that the Bi(2)S(3) nanowire network has a pronounced increase in conductance upon exposure to visible light, and possesses a very fast response time of about 2 ms. This work provides a simple and economic method to fabricate a high performance optical switch array and could offer great potential for a low cost, mass-manufacturing process.
