Abstract: We demonstrate the multiple plasmonic effect on the photocurrent properties of photoanodes containing Ag or Au nanoparticles (NPs) loaded onto titanium dioxide film (Ag-TiO2 or Au-TiO2) on Au grating surfaces. Ag-TiO2 or Au-TiO2 nanocomposite particles are prepared by a flame spray pyrolysis route. The structures and morphologies of the prepared products are characterized by high-resolution transmission electron microscopy. The Ag-TiO2 or Au-TiO2 composite NPs are deposited by spin coating onto the Au grating surfaces. The photoanode electrode is a layered structure of blu-ray disc-recordable grating substrate/Au/Ag (or Au)-TiO 2/dye/electrolyte/indium-tin oxide. The plasmonic effect is induced when Ag or Au NPs are located within the propagating surface plasmon (SP) field on the Au grating surface. The short-circuit photocurrent is increased by exciting the grating-coupled propagating SP on the Au gratings and is further enhanced by positioning the Ag or Au NPs within the grating-coupled SP field.
