Plasmon-induced spatial electron transfer between single Au nanorods and ALD-coated TiO2: dependence on TiO2 thickness.
We employed single-particle photoluminescence (PL) measurements to investigate the interfacial electron transfer between single Au nanorods (NRs) and TiO2 coated by ALD. Analyzing the energy relaxation path of plasmon-generated hot electrons as well as the PL intensities allowed for the detection and study of the interfacial electron transfer process spatially.
