Evaluation of carbon materials using laser Raman spectroscopy.
Solving customer problems with advanced analysis and "analytical skills"! Introducing effective evaluation methods for carbon materials.
"Raman spectroscopy" is an effective evaluation method for carbon materials as it sensitively reflects their structure. It is an analytical technique that utilizes Raman scattered light emitted from a substance when laser light is irradiated onto it. The Raman scattered light appears shifted by a specific frequency based on the vibrations and rotations of the molecules that make up the substance. The degree of this shift is used to perform molecular structure analysis. DLC, fullerenes, graphite, carbon nanotubes, and diamonds are well-known carbon materials. The Raman spectrum shows the G band (1580 cm-1) that commonly appears in graphite and the D band (1360 cm-1) that is attributed to disorder and defects in the graphite structure. The peak intensity ratio of the D band to the G band (R value: ID/IG) and the full width at half maximum can be used to evaluate the crystallinity and quality of various carbon materials. [Features] ■ Identification of micro impurities (organic compounds or metal oxides) as small as 1 µm ■ Identification of carbon species, evaluation of crystallinity of carbon materials, and analysis of graphitization degree *For more details, please download the PDF or feel free to contact us.
