Deposition of silver on the surface of microparticles of zirconium and molybdenum oxides during their synthesis by laser ablation in liquid

The deposition of silver on the surfaces of micro- and nanoparticles of zirconium, molybdenum, and their oxides, obtained by laser ablation of pure metals in aqueous solutions of silver nitrate, is investigated experimentally. Different irradiation regimes and reagent concentrations are approved. The experimental results indicate a possibility of continuous or partial coating (decorating) with silver the surfaces of nanostructures of oxides of the aforementioned metals; using such systems as substrates, one can increase the Raman scattering amplitude. Silvercoated zirconium and molybdenum oxides can be applied in the diagnostic techniques based on the phenomenon of surfaceenhanced Raman scattering.
