Figure 7: SEM image of a bare (a) and an electroless silver plated (b) NW. Inset of (b): the sketch indicates the laser polarization direction. (c) SERS dependence of a single NW/Ag composite on the laser polarization angles for Benzenethiol (BT) molecules at a wavelength of 785 nm. (d) Plot of intensity of SERS representative lines of BT (red) and rhodamine 6G (R6G) (blue) versus angles and the data were normalized to the maximum intensity. (e) SERS dependence of a single NW/Ag composite on the laser polarization angles for R6G molecules at a wavelength of 785 nm.
