| 摘 要： | 在玻璃、白宝石和石英基片上,利用化学沉积法和溶胶法制备了纳米结构活性银膜,系统地研究了两种不同方法制备的单壁碳纳米管(SWNT)的表面增强拉曼光谱(SERS)的G带和D带.同一样品的G带,在不同基片上的峰移量不同,在白宝石基片上移动更大,峰强更高,可以更敏感地反映SERS效应.D带的峰形随基片不同而改变.金属性管的含量较高的样品,其D带光谱的峰移较半导体性管含量较高的样品更显著,表明金属性碳纳米管与SERS活性银膜的界面相互作用更强. |

| Abstract: | Surface-enhanced Raman Scattering of single-walled carbon nanotubes(SWNTs) on silver films deposited on various substrates, including sapphire, quartz and glass, has been studied systematically. The characteristic features of Gband and Dband have been analyzed and compared with arc discharge and laser ablation samples. Dband is much more sensitive than Gband. The position and the intensity of the Gband in SERS spectra depend on substrates. The peakshift and absolute intensity of Gband on sapphire is obviously larger than that on glass. The contribution of high frequency vibrations to the Dband is also dependent on substrates. Compared to the SWNTs sample with high semiconducting tube concentration, the sample with high metallic tube concentration has a stronger interaction with silver films. |
