Effects of dual implantation with Ag and Ni ions on the optical absorption of silica glass were investigated. The surface plasmon absorption spectrum after the dual implantation does not correspond to the sum of the spectrum for only Ag ion implantation and that for only Ni ion implantation. The experimental result suggests that morphology and/or the composition of Ag nanoparticles were changed by the subsequent Ni ion implantation. Furthermore, the result of positron annihilation coincidence Doppler broadening profile of Ag and Ni ion implanted sample also shows that the synthesized Ag nanoparticles is affected by the Ni implantation.
