Abstract AITranslate

In this paper, different sizes of Ag nanoparticles grown on TiO2 film have been fabricated using UV-photoreduction method and studied by UV–vis absorption spectroscopy, ultrafast transient absorption spectroscopy and surface-enhanced Raman scattering (SERS) spectroscopy. The results demonstrated that the plasmon-exciton coupling degree can be well manipulated by changing Ag nanoparticle size, because the surface plasmon resonance (SPR) peak can be controlled by Ag nanoparticle size. The strongest plasmon-exciton coupling occurred when the SPR peak of Ag nanoparticles superposed with the absorption peak of exciton of TiO2 film, which is the optimal catalytic platform for surface catalytic reactions. Our findings might promote a deeper understanding of the reaction mechanism for plasmon-exciton co-driven surface catalytic reactions.
