The effect of Ni pre-implantation on surface morphology and optical absorption properties of Ag nanoparticles embedded in SiO2

- Ag concentration increased significantly due to the Ni pre-implantation.
- Deposition and accumulation process of Ag atoms depends on Ni fluences.
- The incorporation of Ni elements in Ag NPs can damp SPR absorption intensity.
- AgNi alloy NPs embedded in SiO2 have been created by sequentially implantation.
- Unique SPR absorption with dual peaks centered at 406 nm and 563 nm was observed.
