🔬 Raman Microscopy Lab

Intro

In 1995 I started the Raman Microscopy Laboratory for the study and characterization of materials by Raman microspectroscopy. I am specially interested in nanomaterials and microestructured materials, i.e., with inhomogeneities of the order of a few micrometers in composition, orientation, stress, crystallinity, etc.

Experimental equipment

The lab started with the acquisition of a Renishaw Ramascope 2000 Raman microspectrometer, with the possibility of point by point spectral mapping (confocal microscopy with lateral and depth resolution).

• Excitation wavelength: 514.5 nm (green) and 633 nm (red)
• Spectral resolution: 3 cm^-1
• Spatial resolution: 0.6 μm (in the green)

Examples

The following figures illustrate the application of Raman microscopy to chemical imaging in materials science. The data were obtained at the Raman Microscopy Lab of the Materials Science Institute of Madrid, CSIC, in collaboration with other groups.
