摘　　要：研究了几种卤化物对水扬酸分子表面增强喇曼信号的影响,给出了表面增强喇曼谱(SERS)强度随卤离子浓度的变化及对时间的变化过程.并且对影响表面增强喇曼信号的机理进行了一定的分析.The effect of three kinds of halides on SERS signal of molecule salicylic acid was investigated. It was observed that the SERS signal was quenched, instead of enhanced when halide anions were added into the silver sol and salicylic acid system. The efficiency of quenching related to the concentration of halide anions was studied. Time-dependence confirmed that the formation of quenching is probably a fast process.
