Polarization-Dependent Surface-Enhanced Raman Scattering via Aligned Gold Nanorods in Poly(Vinyl Alcohol) Film
Source abstract
Abstract
A low-cost and effective surface-enhanced Raman scattering (SERS) substrate consisting of aligned gold nanorods is obtained by stretching the poly(vinyl alcohol) nanorods composite film doped with the probe molecule. The SERS intensity of characteristic vibrational band of the probe is observed obviously dependent on the angle (θ) between incident polarization and major axis of nanorod. The relationship between them manifests a cos2θ dependence. The result is illustrated from both the localized field enhancement and optical antenna effect of gold nanorod. The finite element method calculation is also performed to further confirm the conclusion.
