TiO 2 nanopore arrays decorated with plasmonic Ag nanoparticles have been fabricated as photo‐induced enhanced Raman spectroscopy (PIERS) substrates. These hybrid nanostructures can achieve 8‐fold PIERS enhancement over normal SERS due to the light‐induced charge transfer from TiO 2 to the Ag nanoparticles upon UV irradiation. Furthermore, this robust and recyclable PIERS substrate is versatile and can detect multiple toxic substances at trace levels. The PIERS technique may become an effective way to enhance Raman scattering, which has the great potential for practical portable Raman detection.
