摘要： 采用近红外激光(1064nm)激发和扫描式双光栅单色仪研究了卤素、卤酸根离子及吡啶对结晶紫近红外表面增强喇曼散射光谱(NIR-SERS)的影响.揭示了这些离子(或分子)与结晶紫及银表面的相互作用.Cl-、Br-、I-、BrO3-离子及吡啶均能引起结晶紫NIR-SERS的明显增强,而ClO3-和IO3-离子则不能.观察到NIR-SERS中化学增强的直接证据,并估算了化学增强因子.Cl-、Br-、I-和BrO3-离子引起结晶紫NIR-SERS的化学增强因子分别约为49、77、15和36.

Abstract: The influence of halide and halate ions as well as pyridine on near-infrared surface enhanced Raman scattering(NIR-SERS) of crystal violet was studied with NIR excitation and a scanning double grating spectrometer. The interaction of crystal violet with these ions(or the molecule) and the interaction of crystal violet with colloidal silver surface have been revealed. Cl-, Br-, I- and BrO3- ions as well as pyridine give rise to a large enhancement of the Raman modes of crystal violet while no Raman bands of it could be observed in the presence of CIO3- and IO3- ions. The chemical enhancement in the NIR-SERS was found and its enhancement factors caused by Cl-, Br-, I- and BrO3- ions were estimated to be about 49, 77, 15 and 36, respectively.

Key words: Crystal violet, Halide ion, Halate ion, NIR-SERS
