英文摘要：

silver nano-particles with average diameter of about 60 nm were compacted in a high-strength mold under different pressures at 523 K to produce nano-structured Ag solid materials. The structure and characteristic of the nano-structured Ag solid materials （NSS-Ag） were studied using X-ray diffraction （XRD）, scanning electron microscope （SEM） and Raman spectrometer. The NSS-Ag could be used as highly efficient surface-enhanced Raman scattering （SERS） active substrates. The common probe molecules Rhodamine 6G （R6G, 1 ×10-10 mol/L） were used to test the SERS activity on these substrates at very low concentrations. It is found that the SERS enhancement ability is dependent on the density of NSS-Ag. When the relative density of NSS-Ag is 83.87%, the materials reveal great SERS signal.
