N2 - Surface-enhanced Raman scattering (SERS) on gold nanohole and nanodisk arrays with precisely controlled size, spacing and shapes of rod, circle, and triangle fabricated via focused ion beam was investigated by 632- and 785-nm lasers. Results demonstrate that nanodisks and nanoholes exhibit strong SERS signals at 632-nm excitation, but only triangular nanoholes present SERS signals at 785-nm excitation. The normal incidence transmission spectrum of nanoholes shows the extension of near-infrared wavelength, but not for nanodisks. The broadband wavelength of plasmon resonance and space confined by triangular nanoholes suggest promise for being a functional component in biosensing, Raman spectroscopy, and photonic devices.
