Rescearchproject " Surface Enchanced Raman Scattering"

    Project Details

    Description

    Research Project Surface Enhanced Raman Scattering: Use of Raman Spectroscopy and Surface Enhanced Raman Spectroscopy for the Characterization of Photographic Components and Processes. In silver halide (AgX with X = Cl, Br, I) photography, most of the processes are controlled by the interaction of Ag or AgX crystals or sols and numerous organic and inorganic species (sensitizers, stabilizers, polymers). The aim of this project is to establish the possibilities of Raman spectroscopy (RS) and surface enhanced raman spectroscopy (SERS) in this field. The techniques are used for the characterization of: * the adsorption and the surface structuration of sensitizers, stabilizers and gelatine on AgX; * the mechanisms at the basis of the water repulsing properties of silver images on printing plates and the stability of the silver crystallites as building stones of the silver image; * the analytical possiblities versus Fourier Transform Infrared Spectroscopy = FTIR (for inorganic components, aqueous solutions, layered materials).
