Raman Spectroscopy

Raman Spectroscopy (picture)

Raman is a powerful Spectroscopic tool for the characterization of materials from different fields: Chemistry, Life Sciences, Material Science, Physics, Micro-Electronics, Semiconductors, and more.

When coupled with confocal microscopy, Raman Spectroscopy enables the ability of compound analyses and distribution.

The Raman Spectrum can be acquired when high flux monochromatic light interacts inelastically with molecular vibrations or phonons in the matter that contains polarizable compounds. This results in radiation higher or lower in energy, that is detected in the spectrometer. The elastic radiation scattered (“Rayleigh Scattering”) is filtered out, and the peaks observed normally arise from different vibrational modes in the materials sampled.

The Raman spectrum provides detailed information about chemical structure, phase and polymorphs, crystallinity and molecular interactions.

Our Scientific Equipment Center possesses a LabRAM Soleil Confocal micro-Raman (Horiba, France) Equipped with 325nm 532 and 785nm lasers and a motorized XY sample stage and motorized focusing for mapping. LabRAM Soleil can measure either Raman spectrum or photoluminescence of samples in different morphologies and phases such as solid, powder, liquid samples including water solutions, and gases.
