We report the self-assembly of aligned arrays of silver nanoparticles governed by a reaction-diffusion-precipitation process. The average 2 μm wide bands containing ~160 nm diameter nanoparticles are highly periodic with ~0.9 - 3 μm spacing. Morphological and analytical characterization of the particles has provided crucial information for the formulation of a series of reactions explaining the band formation. We propose that the silver/silver oxide colloids in the bands turn into elemental silver particles upon UV illumination.
