(Color online) (a) SEM image of the silver particles present in the solution after of photoreduction. (b) E-SEM image of the laser-irradiated area of a glass substrate exposed to a fluence of . The substrate was inserted into the solution after of photoreduction. (c) Photograph demonstrating that silver decoration only occurs at the laser-irradiated areas. The yellow discoloration is due to absorption by silver surface plasmons.
Optical absorption spectra obtained from the laser treated areas of glass substrates inserted into solutions after (a) , (b) , (c) , and (d) of photoreduction.
Raman scattering spectra from (a) silver decorated glass and (b) untreated glass dipped into a dilute R6G solution. The laser treatment in (a) was started after of photoreduction of the solution.
