摘要

The advanced synthesis of multimetallic nanostruc-tures moulded by combining the individual noble metals attracts a considerable attention to various light interactions based applications due to their improved optical response and cost effectiveness in place of bare of noble metals. The selection of noble metal nanoparticles for their best use in plasmonic applications is being made on the basis of surface plasmon resonance peak position, its intensity and full width at half maxima (FWHM). Therefore, in the present study, the plasmonic response of Ag-Cu alloy coated with noble metals has been studied using extended Mie theory. The effect of shell thickness on the plasmonic peak position, scattering efficiency, and FWHM has been examined and found that the plasmonic peak shifts towards the longer wavelength region along with enhancement in scattering efficiency in all the considered bimetallic core-noble metal shell nanoparticles.
