Cleaning of carbon nanotubes near the π-plasmon resonance
The elimination of carbon impurities and defects in as-produced carbon single-walled nanotubes by employing a 248 nm excimer laser treatment is shown by a reduced full-width-at-half-maximum of the Raman D-band up to 755 mW/cm 2, and a decrease in the intensity of the D-band to the G-band. The cleani...

| description | The elimination of carbon impurities and defects in as-produced carbon single-walled nanotubes by employing a 248
nm excimer laser treatment is shown by a reduced full-width-at-half-maximum of the Raman D-band up to 755
mW/cm
2, and a decrease in the intensity of the D-band to the G-band.
The cleaning of bulk carbon single-walled nanotubes (SWNTs) by use of a 248
nm excimer laser is verified with imaging, and quantitative evaluation of morphology and composition. A 5% change in responsivity of a pyroelectric detector coated with SWNTs is presented as a novel assessment of the change in SWNT coating topology. Changes in purity are shown by reduced full-width-at-half-maximum of the Raman D-band for 248
nm exposure up to 755
mW/cm
2. The 248
nm (5
eV) photon–plasmon resonance is considered as a mechanism for the reduction of impurities and an intermediate stage of purification. |
