Abstract:
The intensity and excitation wavelength dependence of the surface-enhanced Raman effect is measured on microlithographically prepared gold and aluminum particle surfaces. Comparison of enhancement relative to identically fabricated silver surfaces gives good agreement with particle-plasmon theories of surface-enhanced Raman scattering.
