Abstract
Laser-ablated silver particles were prepared to characterize chemiadsorption of nucleophilic anion and its evocable spectroscopy. Besides the gradual decrease of particles’ plasmon resonance absorption with the increase of anion, some new absorption bands, assigned to different mechanisms, appeared and shifted due to chemiadsorption effect and aggregation of particles. At the same time, gradual changes and new appearance of luminescence bands indicate that, the hybridization of surface energy states on modified metal surfaces did happen. A chemiadsorption model and a hybridization mechanism were assumed to explain these phenomena.
