Abstract |
Plasmonic nanogap of Ag nanoparticle (AgNP, diameter: 80 nm) – phthalazine – Au thin film (AuTF, thickness: 10 nm) was illuminated with a light with λex = 632.8 nm and the evolution of the surface-enhanced Raman spectrum (SERS) is monitored. Appearance of new peaks of 489 cm-1 and 754 cm-1 were observed and were attributed to the photoproduct. Based on density-functional theory (DFT) simulation, we identify that the photoproduct is the dimers of the phthalazine, generated by the plasmonic hot-electron transfer from metallic surfaces to phthalazine. |
