Transition across a sharp interface: Data from Raman and Brillouin imaging spectroscopy.

ABSTRACT: Brillouin and Raman imaging are powerful techniques for the investigation of complex materials and they are widely used in material science and biophysics [1], [2], [3], [4], [5], [6], [7]. When dealing with microstructures, the results interpretation requires an accurate understanding of the interaction processes in presence of acoustic and chemical boundaries between different materials [8], [9], [10], [11], [12], [13], [14], [15]. The data here reported are obtained while scanning with sub-micron resolution the sharp interfaces between vitreous-SiO₂/Water and Polyethylene (PET)/Glycerol. Molecular and acoustic vibrations were observed by means of a recently developed micro-spectrometer, which acquires simultaneously Raman and Brillouin spectra on the same point with high spat
