Abstract


In this study, the scattering properties of three different gold nano-particles have been studied. The proposed nano-particles are spherical, conical and cylindrical. The simulation results indicate that as the parameter of these nano-particles are changed so different LSPR peaks and shifts achieved in the scattering spectra. So this shows that the resonance modes are strongly reliant on the parameters of the proposed nano-particles. Moreover we have compared the scattering spectra of all the three nano-particles on the basis of their volume. The spherical nano-particle got wide spectral width, shift and high amplitude in the scattering spectra due to which it can be used for biomedical applications.
