Abstract

To dope silicate glasses with mono- and/or multivalent ions, an approach based on field-assisted solid state ion exchange (FASSIE) is used. The diffusion of dopant ions originating from a film deposited onto the glass surface takes place owing to an external electric field across the glass slide. After doping, metal precipitation to form nanoparticles is induced by irradiation with either energetic ion or high power laser beams. The characterisation of soda-lime silicate glass samples doped with different metals was performed by Rutherford backscattering spectrometry, optical absorption and transmission electron microscopy, in order to correlate the irradiation parameters to the cluster formation process.
