title: Mixing does the magic: a rapid synthesis of high surface area noble metal nanosponges showing broadband nonlinear optical response.
abstract: Here we report an instantaneous formation of high surface area metal nanosponges through a one-step inexpensive method in a completely green solvent, water. Merely by optimizing the concentration of the precursors and the reducing agent, we were able to generate a three-dimensional porous structure made up of nanowire networks. This is a general process, involves a simple, room temperature reduction of metal salts with sodium borohydride, and is therefore scalable to any amount. Further, these nanoporous metals because of their network structures show optical limiting behavior of a true broadband nature that would find applications in optoelectronic nanodevices.
