Characterizing the chirality distribution of single-walled carbon nanotube materials with tunable Raman spectroscopy

We have developed a methodology to use resonant Raman spectroscopy with a tunable excitation source to characterize the chirality distribution of a synthesized single-walled carbon nanotube (SWNT) material. Isolated SWNTs are either dispersed or directly grown on substrates with markers. The samples are then placed on an automatic scanning stage of a confocal Raman microscope. Resonant Raman si...

Revealing the impact of catalyst phase transition on carbon nanotube growth by in situ Raman spectroscopy.

The physical state of the catalyst and its impact on the growth of single-walled carbon nanotubes (SWNTs) is the subject of a long-standing debate. We addressed it here using in situ Raman spectroscopy to measure Fe and Ni catalyst lifetimes during the growth of individual SWNTs across a wide range of temperatures (500-1400 °C). The temperature dependence of the Fe catalyst lifetimes underwent ...

Supramolecular chirality measured by diffuse reflectance circular dichroism spectroscopy.

Supramolecular chirality of crystals which display chirality only in the solid state was for the first time measured by diffuse reflectance circular dichroism (DRCD) spectroscopy for sublimable 1 : 1 pyrene (PYR)-p-benzoquinone (Q) complex, and its integrity was proved.

Size And Chirality Effects On Raman Spectrum Of Double-Wall Carbon Nanotube Bundle

We study the tube size and bundling effects on Raman active breathing-like phonon modes (BLM) and tangential-like phonon mode (TLM) of double-walled carbon nanotubes (DWCNT) in the framework of the bond polarization theory, and use the spectral moment’s method. The Raman active modes are calculated for different diameter and chirality of the inner and outer DWCNT tubes. The dependence of the Ra...

Characterization of carbon nanotubes by Raman spectroscopy

Application of Raman spectroscopy to analyse carbon nanotubes has been presented. Having a mixture of various carbon nanotube samples, one can easily distinguish, in a quick experiment, presence of singlewalled, doublewalled and multiwalled carbon nanotubes (SWCNT, DWCNT, MWCNT, respectively). The so-called G-line is a characteristic feature of the graphitic layers and corresponds to the tangen...
