一类菁染料的SERS光谱研究

The SERS Study of Cyanine Dyes

本文报导了一类菁染料在银溶胶中和吸附在硝酸刻蚀的银和铜箔上的SERS 光谱以及两种方式的比较。对硝酸刻蚀粗化银和铜箔表面的最佳条件进行了讨论,区别于银溶胶,用粗化银和铜箔测得了共振 SERS 光谱。提出了菁染料分子在铜、银表面吸附的可能方式。

The SERS spectra of a series of cyanine dyes in silver sol and ad- sorbed on silver or copper film etched by nitric acid are reported and compared. The optimized conditions on nitric acid etched silver and copper films for SERS are discussed.Instead of silver sol,on roughened silver and copper films,we obtained good surface enhanced resonance Raman spectra.The possible adsorb- ing structure of the dyes on metal surface is suggested
