Large-scale periodically structured metal films with enhanced optical transmission in visible frequencies were fabricated by depositing silver onto colloidal crystals. The obtained transmission properties are similar to those observed through periodical hole arrays in planar metal films. We have experimentally observed two enhanced transmission pass bands in visible frequencies in these metal films due to the excitation of surface plasmon polaritons. The peak positions of the pass bands depend on the size of the colloidal spheres. The transmission spectra highly depend on the incident angle for p-polarized light but are weak for s-polarized light. Our fabrication method provides a promising approach for the fabrication of large-scale low-cost plasmonic crystals with submicrometer periodicity.
