Film formation of Ag nanoparticles at the organic-aqueous liquid interface.
We report a wet-chemical method to make films by spontaneous assembly of passivated Ag nanoparticles at the organic-aqueous liquid interface. The interfacial films exhibit a blue opalescence and are characterized with transmission electron microscopy and UV-vis spectrophotometry. Measurements indicate that nanoparticles in the interfacial film can form superlattices and in some cases nanostructures.
