Influence of substrate on the optical properties of non-aggregated silver nanoparticles
Published online by Cambridge University Press: 15 November 2013
Abstract
In this paper, experimental results on the influence of the substrates of different refractive index on the optical properties of two-dimensional silver nanoparticle array are presented. It is shown that plasmon mode that arises from cooperative interactions between closely spaced nanoparticles exhibit different dependences on the incident angle of light. Those dependencies can be qualitatively explained by the concept of mirror images induced in a substrate. Semiconductor (ITO) substrate possesses higher refractive index which even more affects the optical response of silver nanoparticle array.
