Abstract: | Silver particles in soda-lime glass, less than 10 nm in
size, were prepared by ion implantation. The implantation dose
was in the range of 0.5 to 2×1016 Ag
ions/cm2 and the beam current density
was varied from 0.5 to 2A/cm2. Here,
the beam current density strongly influences ion diffusion and
particle precipitation as well as compressive stress generation
around the particles due to thermal effects resulting from the
deceleration of silver ions. Stress relaxation can be achieved
by increased dose rates or thermal processing at elevated
temperatures. Based on RBS and HREM results, a possible route to
homogeneous distribution of Ag nanoparticles within the glass is
discussed with respect to their interesting optical properties. |
