Abstract
Methods for the fabrication of transparent conductive metal nanowire networks are provided, as well as metal nanowire networks fabricated by such methods. A metal nanowire network can be immersed in a solution and illuminated for a duration of time. Selective nucleation and growth of metal nanoparticles can be induced at the junctions between metal nanowires.
Claims16
A method of fabricating a conductive metal nanowire network, the method comprising:
- forming a transparent metal nanowire network comprising a plurality of metal nanowires and a plurality of junctions where metal nanowires meet;
- immersing the network in a reaction solution;
- illuminating the immersed network with light for a duration of time sufficient for selective growth of metal nanoparticles at at least a portion of the junctions;
- removing the network from the reaction solution;
- and
- drying the network.
