(a) Top view(upper) and cross-section(below) SEM images of (1) normally deposited Ag film and (2–5) Ag nanorods arrays deposited at different rates of 1, 1.7, 2.4, and 3.1 Å/s, respectively. Si/SiO2 was used for the substrate. (b) SERS spectra of R6G absorbed on Ag in (a). (c) SERS efficiency of each Ag substrate.
