Favored Structure of Ag Nanoparticles Embedded in SiO 2 by Implantation: Single Crystal with Contracted (111) Lattice

The structure of Ag nanoparticles, embedded in crystalline SiO 2 by high-dose implantation, was investigated. It was found that single crystal is favored over multiple-twinned particles. In addition, the contracted (111) lattice spacing of the Ag nanocrystals was measured by x-ray diffraction.
