Simulated Investigation of Optical Properties in Noble Metallic Alloy Nanosphere

  • Published:
Journal of Applied Spectroscopy Aims and scope

Extinction efficiencies of Ag–Cu and Ag–Au alloy nanospheres are studied based on the Mie theory. The effect of the radius size and the alloy composition on the extinction efficiency has been considered. In alloy nanoparticles such as Ag x Au 1–x nanospheres, the extinction efficiencies vary with the Ag component x. The full width half maxima of the extinction efficiency band becomes broad with decrease in x, however the extinction peak value decreases at the same time. The optimal radius was investigated when double equal extinction peaks arise and the modulation effect of the extinction efficiencies was found. While the Ag component x increases, the extinction peak value becomes greater, but the separation distance between the peaks decreases.
