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。
In this paper, the UV-Vis absorption spectra and SERS spectra of hydroquinone adsorbed on Ag glue during the development of hydroquinone were recorded and confirmed. The effects of Ag ~ + and Br ~ - on the SERS spectra and the SERS quenching effect show that the SERS activity of the developed Ag colloids formed by the reduction of AgBr sols is negative. The SERS activity of quinone hydroquinone adsorbed on the Ag colloids Enhancement mechanisms, mainly molecular enhancement of chemically active sites.
