“…Compared to the monometallic nanoparticles, these nanoparticles offer an additional degree of freedom for adjusting the localized surface plasmon resonance (LSPR) wavelength by altering the ra tio of the two metals [1]. These are helpful in plasmon-enhanced fluorescence spectroscopy [2] and Raman spectroscopy [3], biomedical applications [4], renewable energy [5], optoelectronics [6], plasmon-driven catalysis reaction [7], information storage [8], fuel cells [9], etc. The alloy nanospheres and nanoshells of small and large sizes were used for these applications.…”

Herein, we report the theoretical investigation of two different types of Au-Ag alloy nanoparticles. In detail, the role of composition and localized surface plasmon damping due to the electron-surface scattering on the far field scattering spectra and near field or local electric field enhancement of the small Au-Ag alloy nanospheres and thin alloy nanoshells is studied with the help of analytical theory developed based on Bromwich formulism.
