What can Raman and PL tell you about NANOTUBES?

The HORIBA Jobin Yvon Raman team have introduced specially optimized configurations of their range of Raman spectrometer systems - matched to the growing demands of CNT research.

CARBON NANOTUBES can be studied more easily than ever before

  • Multi-wavelength operation for probing the diameter and chirality of CNTs

  • TRUE Confocal mapping enabling single CNT and bundles to be located upon a sample

  • Broad spectral range of PL emission and Raman signals even out to the NIR (1.6um and above)

  • Macro chamber liquid cells for solution based and macro studies.

The LabRAM ARAMIS, LabRAM HR and T64000 high performance Raman systems offer world leading performance, resolution and versatility and provide researchers a major advance in Carbon Nanotube (CNT) characterization.

The TRUE confocal microscope design available on each of the systems is perfectly suited to spatially resolved Raman mapping, enabling the location of individual carbon nanotubes and bundles to be established. (below, a single island SWNT is located)

 

The unique optical design and dual detector options of the HORIBA Jobin Yvon Raman systems provides an easy operation across the broadest spectral range - no changing of internal optics, no re-alignment of achromats and no loss in performance. The CCD detector range is optimized for the important Raman measurements, whilst the IR array detector options open up access to the NIR PL range, an important new factor for the comprehensive material characterization. 

Multi-wavelength and NIR PL

The high spectral resolution mode of the HORIBA Jobin Yvon Raman systems is unmatched by any other benchtop Raman instrument. The high sensitivity and longer focal length provides the most precise description of the CNT Raman bands - allowing material changes to be studied with greatest confidence and in all its subtlety.

 

These optimized systems become ideal for probing the radial breathing mode and chirality of SWCNT's.

The Kataura plot gives the theoretical RBM peak position for each (n,m) SWNT at its wavelength of resonance

The Kataura plot sums up all information in the Raman spectrum, predicting semiconducting or metallic behaviour.
