摘要
本文以胞嘧啶的表面增强喇曼光谱(SERS)作为探针,讨论了激光照射对银溶胶SERS谱及银溶胶凝聚的影响,分析了影响的原因,指出激光诱导吸附和激光诱导银胶凝聚在这一过程中起主要作用.待测物的浓度越低,获得饱和SERS光谱所需要的时间越长。
The effect of laser irradiation on silver sols SERS has been investigated with cytceine as a probe. It was indicated that photo-induced replacing-adsorption and Ag sols aggregation play the main role in the effect. The lower the concentration of analyte,the longer the time to get the saturated SERS and the higher the intensity of the saturated SERS.
