【摘要】 <正>一、引言近年来,随着SERS研究的深入和发展,对吸附衬底的选用已由单一的银开始转向铜、金等衬底,以铜为衬底进行SERS的理论和实验研究.首先面临的问题是有哪些因素影响和制约铜表面上的SERS效应?对此问题。到目前为止极少有人进行研究,而从更多还原

【Abstract】 In the study of SERS,the problem which we faced on Ou surface is what factors affeet SERS? To this problem,the careful research has not been reported so far.Solving the problem and developing the SERS study on Cu surface, we carry out a careful experiment on mechanicaly polished rough Cu surfaceto search for the factors which influce SERS effect.The experimental results show that the exist of Cl in aqueous solution of the molecules studied not only affects on SERS intensity,also on the shape of SERS spectrum.It has no influce on SERS effect that if the Cu surface is pre-treated with aqueous solution of KCl.更多还原
