中文摘要	We report experimentally the remote excitation surface plasmon and consequent enhancement of surface-enhanced Raman scattering (SERS) using evanescent wave propagating in quasi-one-dimensional (Q1D) MoO3 ribbon dielectric waveguide. The propagating dielectric waveguide along Q1D MoO3 ribbon is realized experimentally, when the 632.8 nm laser radiates on the one side edge of Q1D MoO3 ribbon. The remote excitation SERS spectra-enhanced by chemical and electromagnetic field mechanisms are measured, respectively, where silver (Ag) nanoparticles are excited by electromagnetic field after propagating 7.3 mu m in the ribbon. The chemical mechanism for the remote excitation SERS is contributed from the charge transfer between the analyte molecule and MoO3 ribbon. The electromagnetic field mechanism for the remote excitation SERS arises from the energy conversion from the propagating dielectric waveguide to the surface plasmon of Ag nanoparticles on the Q1D MoO3 ribbon. It is important to reveal the mechanism of energy conversion from the propagating dielectric waveguide to the surface plasmon for potential applications in micro- and nanoscale devices.
