| 摘 要： | 在用化学沉积法制成的银岛膜上,蒸镀上不同厚度的Pt和Pd,测量了吡啶分子在Pt-Ag,Pd-Ag体系的表面增强喇曼散射(SERS)谱,得到SERS谱随覆盖层厚度的增加而衰减的关系曲线,并与电磁衰减理论计算的结果作了比较。此外,在两个体系都发现了新的振动谱线。我们认为它对应于吡啶在Pt和Pd上的吸附态。

| Abstract: | 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. |
