用扫描隧道显微镜（STM）观察了多壁碳纳米管的发光。光子产额取决于扫描管，但它是恒定的所有沿着管。同时光子光谱学证明发射波长在600-1000 nm范围内，与之前的场发射数据非常一致。发射特性与衬底和STM针尖无关。我们讨论了如何这些新的结果是一致的辐射跃迁涉及碳纳米管中的局域态。
Light emission excited by scanning tunnelling microscopy (STM) has been observed on multiwall carbon nanotubes. The photon yield depends on the scanned tube but it is constant all along the tube. Simultaneous photon spectroscopy evidences emitted wavelengths in the 600-1000 nm range in good agreement with previous field emission data. Emission characteristics are independent of substrate and of STM tip. We discuss how these new results are consistent with radiative transitions involving localized states in carbon nanotubes.
