| Research Abstract |
The purpose of this project was to develop an optical means of chirality sorting of single-wall carbon nanotubes based on optical radiation force. An optical microscope system based on a combination of a laser trapping system and Raman/ near infrared photoluminescence spectroscopy with a tunable CW laser was developed. In addition to the chirality sorting by optical radiation force, chirality-selective photobleaching of single-wall carbon nanotubes by an irradiation of intense laser light. Based on these results, an effective chirality sorting method by a concurrent excitation of aggregation and destruction of carbon nanotubes by means of CW and femtosecond pulsed laser light was proposed.
