摘      要：The bimetallic nanostructures that mix a plasmonic metal with a transition metal in the form of the core-shell nanoparticles are promising to promote catalytic *** it is still unclear how the heat(hot electrons and phonons)transfers on the interface between two *** have designed and synthesized Au@Cu bimetallic nanoparticles with Au as core and Cu as *** using transient absorption spectroscopy,we find that there are two plasmon induced heat funneling processes from Au core to Cu *** is the electron temperature equilibrium(electron heat transfer)with equilibration time of~560 *** other is the lattice temperature equilibrium(lattice heat transfer)with equilibration time of~13 *** plasmon induced heat funneling may be universal in similar bimetallic nanostructures,so our finding could contribute to further understanding the catalytic mechanism of bimetallic plasmonic photothermal catalysis.
