Summary: The photo-induced enhanced Raman spectroscopy (PIERS) effect occurs when plasmonic nanoparticles on a semiconductor are illuminated by UV light before Raman measurement. The PIERS effect typically lasts for about an hour, with the proposed mechanism being the creation of oxygen vacancies in the semiconductor to facilitate charge transfer. However, this hypothesis has not been experimentally confirmed. In this study, gold nanoparticles co-deposited with porous TiO2 as a PIERS substrate exhibit the highest measured intensity and significantly longer duration (at least 8 days). Cathodoluminescence measurements reveal two distinct mechanisms for co-deposited and drop-casted gold nanoparticles, with the oxygen vacancies hypothesis leaning towards confirmation for the latter, while the narrowing of the depletion zone explains the prolonged PIERS effect.

Summary: Flexibility and self-cleaning are important areas of research in the development of plasma substrates in Surface-enhanced Raman scattering (SERS). This study presents a flexible composite Au@Ag/ultrathin g-C3N4/Graphene (AUG) film, based on a PDMS film, used as a highly sensitive SERS substrate for detecting rhodamine 6G (R6G) molecules. The AUG flexible composite film displayed a detection limit of 10-12 M for R6G molecules, maintained 83% of SERS activity after 10 photocatalytic cycles, and had only a 5% decrease in SERS detection performance after 30 days of storage in air. The facile fabrication process makes the AUG composite film an excellent candidate for flexible, inexpensive, and stable wearable SERS sensing systems.
