Multispectral SERS using plasmonic width-graded nanogratings
Abstract
We report on a new class of plasmonic nanogratings in which the gradient in the groove-width enables facile fabrication of multiwavelength surface-enhanced Raman spectroscopy (SERS) substrates. These substrates have the potential of achieving unprecedented detection sensitivity, specificity and speed. The structure of these nano-gratings consist of metal-insulator-metal grooves with a 40 nm central groove width flanked by a series of grooves on …
