| 摘 要： | 本文报道了2,2′菁染料的J聚集体吸附于银胶体的表面增强基频和高阶线性Raman散射效应,分析了基频和高阶线性Raman光谱随染料溶液浓度的变化关系。结果表明,J聚集体分子在银胶体表面具有一个稳定的吸附结构,且侧立吸附于表面,一些低波数振动模式起因于J聚集体分子。高阶线性Raman散射的增强与J聚集体分子的性质有关。

| Abstract: | Fundamental and higher order linear Raman scattering of J-aggregated 2,2′-cyanine adsorbed on the silver colloid has been analyzed on the basis of its concentration dependence. The results indicate that there exists only one kind of stable a-dsorbed J-aggregate structure. Some of the low-frequency bands in Raman spectrum are mainly due to J-aggregated molecule, which also plays an important role in the enhancement of higher order linear Raman scattering. |
