| 摘 要： | 本文记录并确认了对苯二酚显影过程产物醌氢醌吸附在Ag胶上的紫外-可见吸收光谱和SERS光谱。通过Ag~+和Br~-对SERS光谱效应的影响和SERS猝灭效应的研究,认为AgBr溶胶还原后生成的显影Ag胶是SERS活性的;醌氢醌吸附在显影Ag胶上的SERS效应的增强机制,主要是化学活性点的分子增强。

| Abstract: | The UV-VIS absorption spectra and SERS spectra of product quinhydrones adsorbed on the silver sol in the developing process of hydroquinone were recorded and affirmed. The origin of enhancement of SERS effect was discussed by studying the influence of excess bromide, silver ions and lead ions upon SERS of quinhydrones on silver sol. |
