摘要
详细讨论了KCl对银胶中结晶紫分子SERS的影响,通过各种浓度KCl对不同浓度CV分子SERS强度影响的研究,结合光吸收实验结果,发现由Cl ̄(-1)的作用,在银表面形成SERS活位,使SERS强度有几十倍的增强。
Abstract The influence of KCl on SERS of CV in silver colloids is disctissed in detail.The ef-fects of concentration of KCl and CV on SERS and light absorption are studied.It isfound that the active sites are formed on silver surfaces by means of chloride ions,andSERS intensity is enhanced.SUBJECT TERMS:SERS,silver colloids,SERS active sites
