| 摘 要： | 本文通过吸收光谱、表面增强垃曼光谱、荧光光谱等手段研究了银纳米粒子与罗丹明6G（R6G）分子之间的相互作用，结果表明：银纳米粒子表面与R6G分子之间存在电荷转移效应。表现为吸收谱长波方向出现银粒子－R6G复合体的吸收带，R6G分子的拉曼振动模得到显著增强，而其荧光得到明显猝灭；AgN特征拉曼振动带的出现服银米粒子与R6G分子是通过银粒表面的活位与R6G分子中的氮原子配位形成复合体而发生电荷转移的。

| Abstract: | In this paper,we studied the charge transferring between silver nanoparticles and R6G molecules by UV-Vis absorption spectra,SERS and fluorescence spectra.The results indicate that the charge transferring process can be completed by forming complex between silver nanoparticles and R6G molecules.As a result,the absorption band of complex can be seen in the absorption spectra,the Raman modes of R6G are largely enhanced and the fluorescence of R6G is effectively quenched. |
