• We investigated Au/TiO 2 mesocrystals as plasmonic photocatalyst prototypes using single-particle photoluminescence (PL) spectroscopy combined with finite-difference time-domain (FDTD) simulations, and found that introduction of defect states builds up a channel for hot electrons with energies lower than the Schottky barrier height to transfer to the semiconductor. Defect states assist hot electrons with energies lower than the Schottky barrier in transferring from Au nanoparticles to TiO 2 .
