摘要：
We report on the 'on-line' photoluminescence (PL) detection of individual single-walled carbon nanotubes (SWNTs) in water-surfactant dispersions. This was achieved by using a near-infrared confocal laser luminescence microscope specially optimized for the PL spectroscopy of SWNTs. A detection of single nanotubes was possible by using dispersions with a relatively low concentration of nanotubes and reducing the PL acquisition time so that a switch-on-switch-off behavior of emission peaks was observed, which reflected a random diffusion of different nanotubes through the laser focus volume. These results demonstrate the analytical potential of PL spectroscopy using SWNTs as luminescent markers.
