报道的双壁碳纳米管（DWCNTs）的内壳层的荧光是一个有趣的和潜在的有用的性质。采用体相和单分子相结合的方法研究了DWCNT样品中近红外发射体的光谱、化学猝灭、机械刚度、丰度、密度和TEM图像。发现DWCNT内壳荧光比SWCNT荧光弱至少10，000倍。DWCNT样品的可观察到的近红外发射归因于SWCNT杂质。
The reported fluorescence from inner shells of double-walled carbon nanotubes (DWCNTs) is an intriguing and potentially useful property. A combination of bulk and single-molecule methods was used to study the spectroscopy, chemical quenching, mechanical rigidity, abundance, density, and TEM images of the near-IR emitters in DWCNT samples. DWCNT inner shell fluorescence is found to be weaker than SWCNT fluorescence by a factor of at least 10,000. Observable near-IR emission from DWCNT samples is attributed to SWCNT impurities.
