Реферат:
Plasmonic silver nanostructures in surfaces of soda-lime silicate glasses were generated usingAgþ4Naþion exchange and UV laser irradiation (ArF laser, 193 nm) with different number ofnslaserpulses (from 2 to 5000). To identify the correlations between the optical properties (surface plasmonresonance (SPR) parameters) and atomic structure of silver nanoparticles and their agglomerations,characterization of the samples was performed by HRTEM, XRD, optical absorption in visible range andAgK-edge EXAFS spectra. Analysis of the optical spectra was performed using a Mie theory approach,accounting for the most plausible defect centers in silicate glass like hole trap centers and non-bridgingoxygen hole centers. Processing of AgK-edge EXAFS yielded values of Ag-Ag and Ag-O interactionsaveraged over ionic and neutral states of silver. The consistent treatment of HRTEM and XRD data, thebehavior of features in optical spectra and the obtained dependence of Ag-Ag and Ag-O structural pa-rameters upon the number of laser pulses enabled to suggest a mechanism of plasmonic Ag nano-particles formation in silicate glass under UV laser irradiation.
