Localized surface plasmon resonance (LSPR) of palladium parallelepiped nanoparticle have been investigated using Finite Element Method (FEM) in the frame of COMSOL Multiphysics Software. Spectral characteristics (magnitude, peak position and width) of LSPR of a single Pd nanoparticle having the shape of a parallelepiped are investigated in two different cases. The first case studied the size effect on LSPR by fixing the height with varying both length and width. However, the second case studied the shape effect on the LSPR by rounding the corners of the parallelepiped for different radii while fixing its dimensions. The extinction cross-section spectra of these different size and shape nanoparticles are calculated for two orthogonal polarization angles and performed over a broad spectral range from 200 to 900 nm. By increasing the radius corner of the parallelepiped nanoparticle, the simulations showed a blue-shifting of the LSPR for polarization along y axis. Palladium nanoparticles have shown significant potential for various applications such as in the field of biomedical applications, environment protection, sensing and information technology applications.
