SERS study of surface plasmon resonance induced carrier movement in Au@Cu2O core-shell nanoparticles

We designed the shell-dependent Au@Cu2O core-shell nanoparticles (NPs) for SERS study. For the electron-hole pairs in the Cu2O, the plasmon induced resonant energy transfer from Au to the Cu2O and the direct electron transfer simultaneously which can be observed from the SERS intensity.78
