Research Abstract |
The photoexcitation of localized surface plasmon resonance (SPR) peak of metal nanoparticles such as gold produces the locally enhanced electric field. In this study, we fabricate novel metal-semiconductor nanocomposites particles and then try to improve the photoelectrochemical properties of semiconductor particles with the SPR-induced electric field near metal particles. The photochemical properties, such as, photocatalytic activity, PL intensity, and the photon-to-electron conversion efficiency, were greatly dependent on the nanostructure of composite particles, probably due to the enhanced photoexcitation of semiconductor nanoparticles, caused by the SPR-induced local electric field on metal particles.
