摘要
报道了覆金滤纸和滤膜上的C60表面增强拉曼散射(SERS),增强因子达到105 以上。分别以吡啶和CS2 为溶剂媒质,对C60吡啶金胶溶液、C60 (吡啶)金胶滤纸以及C60 (CS2)金胶滤膜3 种体系进行了SERS研究和比较。由于其避开了溶剂和金胶中水的影响,这为金纳米颗粒表面C60 SERS研究提供了一套新的思路。通过群论计算分析,并与C60固体拉曼谱相比较,得到了大量的C60分子信息。
The surface-enhanced Raman scattering (SERS) of C60 coated with gold nanoparticles on filter paper and filter film was reported. As the systems avoided the influence of solvent and water in gold colloid, we obtained high-quality SERS spectra, whose enhancement factors were up to 105. It shows a new method of studying SERS of C60 adsorbed on the surface of gold nano-particles in non-water systems. Based on comparing the SERS of C60 and colloidal gold on filter paper, mixture of colloidal gold, C60 and colloidal gold on filter film (CS2 as solvent) with Raman of solid C60, we obtained abundant information of C60 molecule.
