Impact of Raman Spectroscopy On Technologically
Important Forms of Elemental Carbon |
Diamond, Graphite, engineered
Carbons, nanotubes have characteristic Raman spectra.
Relation between the main features of the Raman spectrum
and the physical-chemical properties of the Carbon
material are discussed to provide an aid for characterising. |

Derivation of Physical Parameters
from Raman Spectra of Hard Carbon Films |
The DiskRam has been engineered
to facilitate and significantly accelerate the acquisition
of the Raman spectra of hard carbon overcoats on disk
media. Subsequent data reduction automates the derivation
of the physical properties of interest. Curve-fitting
the spectrum with D and G carbon Bands, additional
nitrogen bands if required, and a baseline achieves
these goals. The methodology used for the spectral
reduction is reviewed in this note. |

Carbon NanoTubes – What information
does Raman bring? |
Raman spectroscopy is a powerful
tool for the characterisation of Carbon Nanotubes
(CNT). The information provided by a high performance
Raman spectrometer are illustrated with a large range
of examples. Spectral resolution, mapping, multi-wavelengths
excitation and PhotoLuminescence detection are key
points for a thorough analysis of CNT's by Raman spectroscopy.

Raman Diffusion and Photoluminescence
Analysis for Coloured Diamond Investigation
|
Some Diamonds are naturally coloured
whereas some others are colour enhanced by means of
a specific treatment. The defect centers in the structure
of the diamond are different in the two cases. Their
Photoluminescence emission spectrum is different and
thus allow to separate the naturally and artificially
coloured gems. Those differences are enhanced at low
temperature.
