The dynamics of Au/Ag alloy formation under Nd:YAG laser irradiation of a mixture of the monometallic colloidal solutions have been experimentally investigated. The change in absorption spectrum of the colloidal particles has been studied as a function of laser irradiation time, fluence, and concentration of nanoparticles in individual colloids. The characteristic time of the alloy formation is about 10 minutes, without any surfactant.
