Abstract

Plasmonic nanostructures have been used to enhance Raman scattering by the virtue of surface plasmon resonances. This method of surface enhanced Raman spectroscopy (SERS) has paved the way for these plasmonic nanostructures to be used as potential SERS substrates in applications like bio-sensing, diagnostics and other applications. In order to optimize the SERS enhancement, the plasmon resonance of the nanostructures needs to be tuned. The usage of alloy nanoparticles has been an efficient method to achieve this. In this paper we study Ag-Cu alloy nanoparticles with Janus morphology and explore the possibility of tuning the plasmon resonance in order to utilize the nanostructures for dual wavelength SERS applications. © 2022 IEEE.
