In this paper, we investigate the plasmonic coupling effects on the localized surface plasmon resonances (LSPRs) of palladium nanoparticle chains. We show the transmission electron microscopy (TEM) images and the extinction cross-section spectra of near-contact palladium nanoparticle chains from monomer to pentamer. The extinction spectra of chains nanoparticles were measured by far-field polarization spectroscopy over a large spectral range (ultraviolet, visible and near-infrared) and compared with numerical calculations based on finite element method (FEM). For single palladium nanoparticle, the LSPR phenomenon appears in ultraviolet region. By addition of palladium nanoparticles to the chain, we observe a tunable red-shifting on the spectral position due to plasmonic coupling between palladium nanoparticles and a systematic spectral amplitude enhancement with the appearance of new modes of resonance.

ABSTRACTUsing palladium for hydrogen storage requires palladium (Pd) particles exhibiting specific parameters, including surface area, particle size, and particle shape, with increased interest in palladium nanoparticles (Pd NPs). In order to routinely monitor the synthesis of these particles a spectroscopic method is being developed using infrared (IR), Raman, and UV-Vis spectroscopy. By monitoring the production of Pd NPs, the growth of the NPs can be controlled to ensure quality of the product to match the desired finished particle specifications. For the reaction presented, the conversion of the intermediate tetraamminepalladium(II) chloride (PTC) to diamminepalladium(II) chloride (PDC) can influence the Pd NPs properties. This study is first being developed in lab bench scale quantities to allow ultimate control of the Pd NPs.
