摘要：

The dependence of nanoparticle size on surface-enhanced Raman scattering (SERS) from silver film over nanospheres substrate is studied. For a range of nanosphere sizes from 430 to 1,500 nm, optimum SERS signal is obtained with a nanosphere size of 1,000 nm at an excitation wavelength of 532 nm. We have clarified the physical origin of this optimization in an unambiguious way as due to resonant plasmonic excitations from 3D finite-difference time-domain simulations, as well as with the assistance of UV-visible reflectance spectrum.
