Carbon nanotubes--Raman application
Carbon nanotubes (CNTs)_80062.com_澳门葡京63355.com
Model: Raman 532
Laser wavelength: 532 nm
TE cooled CCD: 1204X128 pixels
Sample I: microwave treatment with Ar
Sample II: microwave treatment with Ar and CO
D-band is often used to assess the quality of carbon nanotubes.
Dispersive D-band involves structural defects or disorder.
The D/G of sample I is larger than that of sample II indicated that the defect density is suppressed in the carbon nanotubes treated by microwave in CO atmosphere.
