Abstract
We experimentally and theoretically study the density-dependent optical properties of gold nanoparticle monolayers on silicon at . Both results indicate a density-dependent resonance behavior. The density-dependent resonance suggests that the optical properties of the gold nanoparticle monolayers can be drastically modulated by changing the volume ratio . It also implies, in this composite system, that the total surface plasmon resonance is maximized at a certain .
