摘要: N,N'-二乙基喹啉菁染料分子吸附在硫敏化过的溴化银溶胶上产生强的表面增强喇曼散射,这种散射实际上是在直晒银上产生的。N,N'-二乙基喹啉菁染料分子吸附在硫敏化过的溴化银溶胶和银溶胶上的喇曼谱基本相似。而未经硫敏化的溴化银溶胶和经硫敏化后再被高硫酸钠氧化的溴化银溶胶中测不到N,N'-二乙基喹啉菁染料的表面增强喇曼信号。本实验进一步表明,表面增强喇曼散射方法可以用于感光机理的研究。

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.
