报道了一种新颖且简单的方法来制备在水中具有强可见荧光的良好分散的单壁碳纳米管。发现可见荧光对 pH 值和金属离子有响应，并且氧化的 SWCNT 的发射能力根据激发波长可调，并且发现了一种新颖的自激发和发射过程。
A novel and simple method to prepare well dispersed single-walled carbon nanotubes with strong visible fluorescence in water is reported. The visible fluorescence was found to be responsive to pH value and metal ions, and tunable emission ability of oxidized SWCNTs depending on the excitation wavelength and a novel self-excitation and emission process were found.
