We measured SERS intensities of pyridine on Pt and Pd deposited as overlayers on several silver island films, obtained the damping curve of SERS intensities versus Pt and Pd thickness. The results were compared with the electromagnetic damping theory proposed by Murray. We concluded that the short range damping play a very important role. Moreove, a new mode related to Pt and Pd overlayers were also discovered.
