摘　　要：用不同的方法制备了三种粗糙银表面。在低波数频移区进行了喇曼散射研究,发现在116 cm^(-1)及104 cm^(-1)处有两个较强的峰,并归因于粗糙银表面本身的微结构元-银原子簇的贡献。进一步的实验研究表明,表面增强喇曼散射现泉与银原子簇的存在有着直接的关联。By measuring the Raman scattering from three kinds of rough silver surfacesprepared by different methods, authors find there exist two Raman bands at116 cm^(-1) and 104 cm^(-1), that could only be assigned to the contribution from thesilver microstructures which are in the form of clusters. It is experimentally provedthat the clusters play the role in SERS.
