[Title] The Remarkable Optical Properties of Single-Walled
Carbon Nanotubes
[Speaker] R. Bruce Weisman

[Place] I²CNER Hall, Ito campus, Kyushu University
[Abstract]Single-walled carbon nanotubes (SWCNTs) are a family of artificial nanostructures with unique physical and chemical
properties. They are the subject of intense interest in basic and applied research. Each SWCNT consists of carbon atoms
covalently bonded into a tubular structure with long-range order and a specific diameter, roll-up angle, and electronic band
structure. Most SWCNTs are semiconducting and show band gap photoluminescence (fluorescence) at characteristic
wavelengths in the short-wave infrared. The discovery, interpretation, and properties of SWCNT fluorescence will be
described. Some examples will also be presented showing how nanotube spectroscopy is used to characterize samples and
to study structure-dependent physico-chemical processes.
