| 摘 要： | 本文报道了非水电化学体系中激光照射时间对咪唑在甲醇溶剂中吸附在电化学粗糙了的银电极表面上的表面增强拉曼散射(SERS)效应的影响及咪唑吸附在银电极表面上的SERS谱的连续背景的研究。结果表明,甲醇介质中咪唑吸附在银电极表面上的SERS谱强度随激光照射时间而变化,并且咪唑在甲醇介质中的SERS谱背景较强。初步探讨了咪唑吸附在银电极表面上的SERS效应的增强机制。

| Abstract: | In this paper, we presented the study on the effect of laser irradiation time on the surface enhanced Raman scattering (SERS) spectra of imidazole in meth, anol solution adsorbed on the electrochemically roughened silver electrode surface and the continuous background of the SERS spectra. Experimental results showed that the intensity of SERS spectra of imidazole adsorbed on the roughened silver electrode changes with laser irradiation time and the strong continuous background of the SERS spectra appears. The mechanism of SERS spectra of imidazole adsorbed on the silver electrode in nonaqueous electro-chemical system is proposed. |
