• Highly-pure amorphous silica slides were implanted by 200 keV Ag ions with doses ranged from $1\times 10^{16}$ to $2\times 10^{17}$ ions/cm2. Optical absorption spectra show that Ag nanoclusters with various sizes have been formed. Enhancement of surface enhanced Raman scattering signal by a factor up to about $10^{3}$ was obtained by changing the Ag particle size. The silica was damaged by the implanted Ag ions, and the large compression stress on the silica leads to the shift of Raman peaks. New bands at 1368 and 1586 cm-1, which are attributed to the vibration of Ag–O bond and O2 molecules in silica, are observed in the samples with doses higher than $1\times 10^{17}$ ions/cm2.
