摘要：

Surface-enhanced Raman scattering (SERS) was observed for oxazine 720 molecules adsorbed on a copper film pierced by nanohole arrays. Each of the arrays had a different hole periodicity. The dependence of SERS intensity on hole periodicity was examined using two experimental geometries: forward-scattering and backscattering. Electric field intensity perpendicular to the surface of the metal was calculated for each array using the finite-difference time-domain method, and for both geometries, the array with the greatest calculated value matched the array that gave the greatest experimentally observed SERS intensity.
