论文摘要
最近已广泛应用近场光谱法来分析纳米级材料的集体光学性质。然而，小分子的振动仅在与金属谐振剂附近可识别。我们表明，在硝酸硼纳米管（BNNT）中的封装增强了C $ _ {60} $ Fullerene的近场振动光谱，达到了几百个分子的灵敏度极限。此外，只要它们的振动特征位于BNNT的极化缝隙中，就可以鉴定在试管内的化学反应产物。
Near-field spectroscopy has been extensively applied recently to analyze collective optical properties of materials at the nanoscale. However, vibrations of small molecules were only recognizable in close proximity to a metallic resonator. We show that encapsulation in boron nitride nanotubes (BNNT) enhances the near-field vibrational spectra of C$_{60}$ fullerene, reaching a sensitivity limit of a few hundred molecules. Furthermore, products of chemical reactions inside the tubes can be identified, so long as their vibrational signatures lie in the polariton gap of the BNNT.
