Abstract: Nanorings and methods for fabrication thereof, preferably of gold and tungsten, involve deposition on silicon wafer and/or glass substrates using random incidence sputtering deposition and thermal vapor deposition techniques to produce two dimensional tungsten nanotriangle and gold nanoring arrays on the silicon wafer substrates with the size of resulting equilateral tungsten nanotriangles being about 100 nm per side and being spaced about 210 nm from each other, and with the gold nanorings being about 220 nm in diameter, 40 nm wide, 10 nm thick and being spaced about 560 nm from each other.
