Abstract
Nanoscaled AgxAu1−x (0.2<x<0.8) alloy particles were synthesized by putting gold and silver particles into pores of monolithic mesoporous silica by soaking and annealing method. It has been found that in optical absorption spectrum, the surface plasmon resonance (SPR) maximum of AgxAu1−x alloy particles can shift from about 524 nm (SPR maximum of Au nanoparticles) to about 400 nm (SPR maximum of Ag nanoparticles) with increasing concentration of Ag in AgxAu1−x alloy particle. The simulation of optical absorption spectrum of AgxAu1−x alloy particles was conducted based on Mie theory. The calculated values are found to be consistent with the experimental results.
