Image of FIG. 1.
FIG. 1.

(Color online) (a) Schematic illustration of the structure of the Ag nanorod array on a glass substrate and definition of the incident angles. (b) SEM image of the Ag nanorod array fabricated by the OAD technique.

Image of FIG. 2.
FIG. 2.

(Color online) Representative SERS spectra of BPE adsorbed on the Ag nanorod substrate at different incident angles , 0°, 20°, 45°, and 60°. The peak intensity was strongest at around 45°.

Image of FIG. 3.
FIG. 3.

(Color online) Integrated SERS intensity for the BPE band at plotted as a function of the incoming laser incident angle (scattered points). In addition, the ratio of Raman scattering intensity to the incident light intensity as calculated from the modified oscillating dipole model described in the text is plotted (solid curve).

Image of FIG. 4.
FIG. 4.

(Color online) Schematic illustration of the modified Greenler’s model of an induced dipole on a Ag nanorod: case I, where the dipole is perpendicular to the incident plane; case II, where the dipole is on the incident plane. All the induced dipoles are perpendicular to the nanorod.
