氯离子引起结晶紫分子表面增强喇曼散射进一步增强的研究

STUDY OF FURTHER ENHANCEMENT OF SURFACE ENHANCED RAMAN SCATTERING OF CV BY ADDING Cl￣(-1)

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
