Optical Properties and SERS Activities of Thin Au Half-Shell Nanofilms on Glass and Silicon Substrate

Abstract:

Thin gold hollow half-shell nanostructured films are fabricated by deposited gold over regular arrays of polystyrene nanospheres on glass and silicon substrate respectively in an attempt to evaluate their optical properties and SERS activities. Scanning emission microscopy is used to topographically characterize the nanofilms. Optical spectra taken by UV-vis-NIR spectrometer show that the surface plasmon resonance wavelength of films fabricated on glass is shorter than that fabricated on silicon despite the nanoshell thickness is the same on both substrate, and the SERS intensity excited on silicon is stronger than that on glass because the nanofilms are so thin that the silicon can reflect the SERS signal and excited laser.
