  Au nanoparticles onto a silica-glass (SiO2) surface have been formed due to thermal dewetting of Au thin films. Subsequently, high energy Si ion-irradiations on the pristine Au nanoparticles result systematic redshifts of optical responses and concomitant broadening of the optical absorption peaks with ...  Read More
