| Abstract: | 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. |
