Enhanced refractive index sensitivity of elevated short-range ordered nanohole arrays in optically thin plasmonic Au films

A simple development of the colloidal lithography technique is demonstrated for fabrication of perforated plasmonic metal films elevated above the substrate surface. The bulk refractive index sensitivity of short-range ordered nanohole arrays in 20 nm thick Au films exhibits an increase of up to 37%...
