Multiple plasmonic effect on photocurrent generation of metal-loaded titanium dioxide composite/dye films on gold grating surface

We demonstrate the multiple plasmonic effect on the photocurrent properties of photoanodes containing Ag or Au nanoparticles (NPs) loaded onto titanium dioxide film (Ag-TiO 2 or Au-TiO 2 ) on Au grating surfaces. Ag-TiO 2 or Au-TiO 2 nanocomposite particles are prepared by a flame spray pyrolysis...
