Clustering of Silver Nanoclusters Embedded in Soda Lime Glasses Using Ionic Exchange and Helium Ion Bombardment

摘要: Silver nanocluster precipitation in AR Schott glass by subsequently silver ionic exchange and helium bombardment was investigated scanning electron microscopy (SEM), transmission (TEM), UV-visible optical absorption. Helium ion used to induce local defects the matrix promote growth of nano-aggregates. The typical implantation depth estimated at 1 μm Trim simulation. SEM investigations give us concentration profile exchanged samples maximum depth. Optical absorption performed visualize effect He+ fluence on sample spectra compared Drude model varying size refractive index. TEM evaluate distribution nanoparticles, their structure diffraction pattern, size, shape correlate it experimental theoretical curves. observations prove that we are a confinement regime with particle below mean free path bulk metal.
