Single-molecule fluorescence spectroscopy was used to determine the electronic properties of individual single-walled carbon nanotubes. Carbon nanotube structure was determined simultaneously from Raman spectroscopy. Fluorescence spectra from individual nanotubes with identical structures have different emission energies and linewidths that likely arise from defects or the local environment. Unlike most other molecules studied to date, the fluorescence intensity or spectrum from a single nanotube unexpectedly did not fluctuate.
单分子荧光光谱法被用于测定单个单壁碳纳米管的电学性质。同时通过拉曼光谱法确定碳纳米管的结构。具有相同结构的单个纳米管的荧光光谱具有不同的发射能量和线宽，这可能是由缺陷或局部环境引起的。与迄今为止研究的大多数其他分子不同，单个纳米管的荧光强度或光谱出人意料地没有波动。
