Systematic Understanding

In this work, we have investigated the localized surface plasmon resonance profile of promising non-noble metals such as nickel (Ni), iron (Fe), and permalloy (Ni80Fe20) as an alternative plasmonic material. The nanoparticle formed a sphere with varying the diameter from 10 nm to 200 nm with increment 10 nm, and the medium of nanoparticles is air (1+0i). The calculation was carried out by metallic nanoparticle boundary element method package. Furthermore, our result shows that increasing diameter of particles (iron, nickel, and permalloy) would increase the efficiency of ratio scattering to absorption, and the LSPRs peak led to shift to lower energy (red-shift). The ratio of scattering to absorption indicates a strengthening of radiative damping in large particle-size which largely used in biological cell imaging. However, iron’s efficiency much lower than nickel and permalloy. For example, at the highest diameter, such 200 nm, the efficiency of iron is just over around 1.25 while nickel and permalloy well under nearly 2.0. In addition, nickel and permalloy’s LSPR happened in visible range. Our results serve a systematic understanding of the shifting spectrum pattern for prospective ferromagnetic materials
