We present a study of optical transmission through metal-coated non-close-packed colloidal crystals. The arrays combine semi-shell particles and circular holes simultaneously. We show that the optical response of the structures can be tuned by altering the size of the semi-shell particles and holes. The non-close-packed colloidal crystals were fabricated using modified nanosphere lithography and reactive ion etching.
