Efficiency enhancements in Ag nanoparticles-SiO(2)-TiO(2) sandwiched structure via plasmonic effect-enhanced light capturing

TiO(2)-SiO(2)-Ag composites are fabricated by depositing TiO(2) films on silica substrates embedded with Ag nanoparticles. Enhancement of light absorption of the nanostructural composites is observed. The light absorption enhancement of the synthesized structure in comparison to TiO(2) originated fr...

description TiO(2)-SiO(2)-Ag composites are fabricated by depositing TiO(2) films on silica substrates embedded with Ag nanoparticles. Enhancement of light absorption of the nanostructural composites is observed. The light absorption enhancement of the synthesized structure in comparison to TiO(2) originated from the near-field enhancement caused by the plasmonic effect of Ag nanoparticles, which can be demonstrated by the optical absorption spectra, Raman scattering investigation, and the increase of the photocatalytic activity. The embedded Ag nanoparticles are formed by ion implantation, which effectively prevents Ag to be oxidized through direct contact with TiO(2). The suggested incorporation of plasmonic nanostructures shows a great potential application in a highly efficient photocatalyst and ultra-thin solar cell.
