密度梯度超离心富集扶手椅型碳纳米管：拉曼光谱证据
Enrichment of Armchair Carbon Nanotubes via Density Gradient Ultracentrifugation: Raman Spectroscopy Evidence
摘要：
我们已经使用共振拉曼散射光谱充分分析了不同的（n，m）物种的相对丰度在单壁碳纳米管样品中，金属富集密度梯度超浓缩。引人注目的是，数据清楚地表明，我们的密度梯度超离心过程中富集的扶手椅和近扶手椅物种的金属馏分。我们观察到扶手椅型碳纳米管占每个（2n + m）家族的50%以上。
英文摘要：
We have used resonant Raman scattering spectroscopy to fully analyze the relative abundances of different (n,m) species in single-walled carbon nanotube samples that are metallically enriched by density gradient ultracentrifugation. Strikingly, the data clearly show that our density gradient ultracentrifugation process enriches the metallic fractions in armchair and near-armchair species. We observe that armchair carbon nanotubes constitute more than 50% of each (2n + m) family.
