Abstract
An important aspect of synthesizing designer nanostructures is fine-tuning their size, composition, and surface area. These parameters often dictate the unique properties of nanoparticles relative to their bulk counterpart. This paper reports the synthesis of porous metal nanorods with well-controlled dimensions, porosity, and photonic properties. The growth of each nanostructure is directed by a polycrystalline sacrificial template of silver with well-defined, tunable dimensions. This template can be selectively etched to isolate a porous hollow nanostructure. The porosity, composition, and photonic characteristics of this nanostructure are adjustable by controlling the reaction conditions.
