摘要: Abstract Plasmonic silver nanostructures in surfaces of soda-lime silicate glasses were generated using Ag + ↔ Na ion exchange and UV laser irradiation (ArF laser, 193 nm) with different number ns pulses (from 2 to 5000). To identify the correlations between optical properties (surface plasmon resonance (SPR) parameters) atomic structure nanoparticles their agglomerations, characterization samples was performed by HRTEM, XRD, absorption visible range K -edge EXAFS spectra. Analysis spectra a Mie theory approach, accounting for most plausible defect centers glass like hole trap non-bridging oxygen centers. Processing yielded values Ag-Ag Ag-O interactions averaged over ionic neutral states silver. The consistent treatment HRTEM XRD data, behavior features obtained dependence structural parameters upon enabled suggest mechanism plasmonic formation under irradiation.
