Description
Summary:Herein, we report the experimental and theoretical study on scattering spectra of single-sprouted potato-shaped Au-Ag bimetallic nanoparticles. In detail, first, the sprouted potato-shaped nanoparticles are synthesized using the wet-chemistry method, and the morphology of the nanoparticles is studied using a field emission scanning electron microscope. Moreover, the scattering images and spectra of single nanoparticles of different sizes are captured using a dark field microscope. The finite element method (FEM) simulations are performed on these nanoparticles and investigated the dependence of the far-field scattering spectra and local field distribution on the morphology of the nanoparticles (i.e. size and shape of the sprouts and the nanoparticle bases or cores on which the sprouts are anchored).
