Abstract
The present invention provides nanoprisms etched to generate triangular framework structures. These triangular nanoframes possess no strong surface plasmon bands in the ultraviolet or visible regions of the optical spectrum. By adding a mild reducing agent, metal ions remaining in solution can be reduced, resulting in metal plating and reformation of nanoprisms. The extent of the backfilling process can be controlled, allowing the formation of novel nanoprisms with nanopores. This back-filling process is accompanied by a regeneration of the surface plasmon bands in the UV-visible spectrum.
Claims12
A triangular nanoframe having an edge length of less than about 200 nm and a thickness of less than about 100 nm and a pore through the center of the {111} face of the nanoframe, wherein the nanoframe is free of pores through the {110} faces.
