In the present work, we report our observations drawn from the numerical simulation of absorption and scattering efficiencies of spheroid shape nanostructures using discrete dipole approximation technique. The absorption and scattering spectra are discussed in terms of shell thickness, composition of core and shell material, aspect ratio and size of the spheroidal nanoparticle (NP). The normalized...
An investigation of the wavelength dependent extinction spectra of coated sphere with different core@shell compositions based on discrete dipole approximation technique has been presented in this paper. We have used combinations of Ag, Au, and SiO2 for this analysis. Specifically, we study the impact of spherical core-shell thickness on its surface plasmon resonance (SPR) peak positions and corresponding...
