%X Ag/SiO2 multilayer thin films were prepared by RF magnetron sputtering. The Ag nanoparticles diffuse towards and mostly assemble near the surface of the Ag-SiO2 films via rapid thermal treatment. Ag nanoparticles with different shapes can be obtained by changing the thickness of Ag and SiO2 layers. It is found that the Ag particles with sharper edges and wider terrace between steps have more electrons at Fermi level. Accordingly, the intensity of resonance absorption is obviously enhanced.
