Abstract:
In one aspect, methods of making semiconducting single-walled carbon nanotubes are described herein. In some implementations, a method of making semiconducting single-walled carbon nanotubes comprises providing a plurality of semiconducting nanotube seeds including (n,m) nanotube seeds and non-(n,m) nanotube seeds. The method further comprises illuminating the plurality of nanotube seeds with a first laser beam having a first wavelength and a second laser beam having a second wavelength, the second wavelength differing from the first wavelength. The first wavelength corresponds to an absorption maximum for a (n,m) carbon nanotube and the second wavelength corresponds to a photoluminescence emission frequency for the (n,m) carbon nanotube.
