摘要： 本文研究了呫吨类染料分子(R110, RB, SRB, R_6G, R101和SF)吸附于化学沉积银岛膜上的表面增强共振喇曼散射(SERRS)光谱。文中详细的介绍了获得SERRS的实验条件, 对谱线的归属作了指认, 并讨论了共振、表面增强、吸附状态和衬底制备条件等因素对SERRS的特征和对喇曼散射截面的增强的影响。结果表明, SERRS是研究强荧光染料分子以及它们与金属表面相互作用的一种新的有效手段。

Abstract: We have studied the Surface Enhanced Resonance Raman Scattering (SERRS) spectra of xanthene dye molecules (R110, RB, SRB, R6G, R101 and SF) adsorbed on chemical deposited silve-island films. In this paper, the experimental conditions for SERRS have been described, the assignments of Raman scattering bands have been done, and the influence of resonance, surface enhancement and the preparations of substrates on the characters of SERRS and on the enhancement of Raman scattering cross-section have also been discussed. The results show that SERRS is a new and effective method for studying the intense fluescence dye molecules and their interaction with metal surface.
