摘要: 研究了2-氨基苯并咪唑(BIMNH2)、LiCl、NaOEt对Ag/EtOH溶胶吸收光谱和表面增强Raman散射(SERS)光谱的影响。结果表明,少量的吸附分子BIMNH2、LiCl、NaOEt均能改变溶胶聚集状态,从而影响其吸收光谱和SERS效应。此外,Cl-还可与Ag、BIMNH2形成表面络合物而增强SERS效应。对Ag溶胶体系SERS光谱的溶剂效应也作了初步研究。

Abstract: The effects of 2-aminobenzoimidazole(BIMNH2), NaOEt, LiCl on the absorption spectra and surface enhanced Raman scattering (SERS) spectra are studied.The experimental results indicate that a samll amount of adsorbed molecules, NaOEt, LiCl can influence the aggregation of silver organosols, and the absorption spectra and SERSspectra.Additionally, Cl- forms surface complex compound with Ag, BIMNH2, as a result, the SERSspectra are enhanced.The effect of solvent on SERS spectra are initially studied.

Key words: Absorption spectra, Surface enhanced Raman spectra, Silver organosol, Sodium ethoxide, Lithium chloride
