Effects of Ag Particles'Shape in Ag-SiO_2 Composite Films on Surface Resonance Absorption Properties
Source abstract
Abstract
Ag/SiO_2 multilayer thin films were prepared by RF magnetron sputtering.The Ag nanopar- ticles diffuse towards and mostly assemble near the surface of the Ag-SiO_2 films via rapid therinal treat- ment.Ag nanoparticles with different shapes can be obtained by changing the thickness of Ag and SiO_2 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.
