Localized surface plasmon resonances (LSPRs) have been observed from nanostructured particles and cavities composed of noble metals such as Au, Ag, Cu, and Pd. Cu nanostructures have been studied due to their characteristic LSPRs, and especially, anisotropic Cu nanoparticles have shown intense dipolar plasmon resonances. Herein, we describe a microemulsion strategy for preparation of colloidal Cu nanoprisms. As a result, intense dipolar resonances were observed by monitoring the optical response of resulting Cu nanoprisms. To explain the relation between resulting morpologies and corresponding optical response, the simulated optical spectra were calculated for the comparison between measured and simulated optical spectra. Spectral enhancement and red-shift of LSPRs were confirmed from measured and simulated spectra with anisotropic control of resulting mophologies.
