Direct-write pulsed laser processed silver nanowire networks for transparent conducting electrodes

摘要

Metal nanowire networks are promising alterna-tives for transparent conducting layers in flexible electron-ics. However, the inverse relationship between transparency and conductivity limits their viability in many critical appli-cations. In this work, we demonstrate a direct-write refining technique in which a solution-processed nanowire network, deposited by spin coating, is exposed to monochromatic UV pulsed laser processing near a plasmonic resonance. Our re-sults exhibit a 75 % reduction in surface resistance along with marginal improvements in optical transparency. The lo-cal nature of the laser technique enables direct-write or large area processing on a variety of substrates including flexible, and organic materials.
