Nanoplasmonics is an emerging branch of photonics that studies the optical properties of noble metals. Nanostructured noble metal materials, which can strongly interact with light and support various plasmon modes, are exceptional candidates for nanophotonic devices. This work describes the latest advances in the fabrication of ordered silver nanoparticles or nanowell arrays using both nanosphere lithography (NSL) and electron beam lithography (EBL). More specifically, three types of new NSL-derived materials are addressed in this thesis: (1) the application of electrochemistry to "fine tune" the structure of silver nanotriangles and the wavelength of their localized surface plasmon resonance (LSPR), (2) the fabrication of ordered arrays of in-plane, triangular cross-section nanowells with the aid of reactive ion etching (RIE), and (3) the anchoring of the truncated tetrahedrons for a more stabile sensing surface. Futhermore, utilizing EBL, studies looking deeper into the fundamental coupling interactions in both one and two dimensional arrays were performed. All of these studies will allow for the logical design of novel plasmonic devices for an array of applications.
