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。
Adsorption of N, N’-diethylquinoline cyanine dye molecules on the sulfur sensitized silver bromide sol produces strong surface-enhanced Raman scattering that is actually produced on direct wash silver. The Raman spectra of N, N’-diethylquinoline cyanine dye adsorbed on sulfur sensitized silver bromide sol and silver sol were similar. The surface-enhanced Raman signal of N, N’-diethylquinoline cyanine dye was undetectable in the non-sulfurized silver bromide sol and in the silver bromide sol which was sulfur-sensitized and then oxidized by sodium sulfate . This experiment further shows that the surface-enhanced Raman scattering method can be used for the mechanism of photosensitive research.
