| 摘 要： | 利用化学沉积法和溶胶法制备了粒径在20～100nm范围内不同的表面增强纳米结构活性银膜，系统地研究了单壁碳纳米管（SWCNT）的表面增强拉曼光谱（SERS）的G—band和D—band、比较玻璃和石英两种不同基片上的结果发现，单壁碳管的SERS谱随银膜粒径的变化有相同的变化趋势，G-band峰移对20～100nm范围内活性银膜粒径的差异不敏感，表明该波段所对应的碳管六元环本征振动比较稳定，与界面的化学相互作用较弱．D—band的峰形随基片和活性银膜粒径不同均有改变，且随着粒径变小，高频振动贡献有增大的趋势，表明无序碳与活性银膜间存在很强的相互作用。

| Abstract: | Surface-enhanced Raman Scattering(SERS) spectra of single-walled carbon nanotubes(SWCNTs) on silver films with different nano-particle sizes from 20-100 nm deposited on quartz and glass substrates were studied systematically.The characteristic Raman spectral features of SWCNT G-band and D-band were analyzed.The two bands show a similar tendency with the change of nano-particle size of silver on quartz and glass substrates.The position and the intensity of the G-band are less sensitive to the films silver particle sizes in the studied range,indicating that hexagonal carbon rings are stable and have a weak interaction with silver films.The shape of the D-band is dependent on the silver size.The smaller the silver particle size,the more the contribution of high frequency vibrations to the D-band,indicating that disorder carbon has a strong interaction with the active silver films. |
