Abstract
Highly luminescent singles of Ag sol with gradual changes were detected when adjusting the granularity and concentration of particles. It can be deduced that these Ag sols, composed of a large amount of silver nanoparticles and clusters, may have their surface energy bands alterable, which might be caused by the interactions between particles. A model that describes the shift of energy band is proposed, and it can be understood as the hybridization of elementary plasmons when interactions occur between particles. Besides, both hybridization and absorption-rescattering mechanisms were proposed to explain the changeable phenomena of photoluminescence with different concentrations.
