摘    要:研究了2-氨基苯并咪唑(BIMNH_2)、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BIMNH_2、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、BIMNH_2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。

关 键 词:吸收光谱  有机银溶胶  SERS

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 SERS spectra. Additionally, Cl- forms surface complex compound with Ag, BIMNH2, as a result, the SERS spectra are enhanced. The effect of solvent on SERS spectra are initially studied.
Keywords:Absorption spectra  Surface enhanced Raman spectra  Silver organosol  Sodium ethoxide  Lithium chloride
