Silver sol-gel was prepared by reduction reaction of nitrate silver with sodium citrate.And silver films were prepared as a surface enhanced Raman spectroscopy（SERS）active substrate by vacuum deposition.Different approaches are taken to analyze particle size on the calculation of the base.In this paper,piperidine is chosen as the detective molecule,SERSs on the silver film and in the silver sol-gel are obtained.The effect of particle size on spectroscopy intensity is analyzed.
