Abstract

Abstract: The Surface Enhanced Raman Scattering of N,N'-diethyl quinocyanine molecules adsorbed on silver bromide sols after sulfur sensitization was detected. It was found that the scattering is from the molecules adsorbed on the surface of print-out silver. The enhanced scattering of the dye adsorbed on silver bromide after sulfur sensitization is similar to that on silver sol. The Raman Scattering can not be,detected when silver bromide sols are not sensitized and the print-out silver is oxidized with sodium persulfate. As this experiment shows,the Surface Enhanced Raman Scattering method can be used in the investigation of photographic mechanism.

Key words: Raman spectra, photography, surface, silver halide
