Theoretical Study of the Anchoring Influence on Plasmonic Resonance Tunability of Metallic Nanoparticles Embedded in a Liquid Crystal Cell
Résumé
In this paper, the localized surface plasmon resonance (LSPR) peak position of an ordered gold nanoparticles array embedded in a nematic liquid crystal (LC) media is investigated using finite-difference time-domain method. The influence of the anchoring effects between nematic LC molecules and glass substrate on the shift of LSPR wavelength is taken into account, and results are compared with the case of a perfect alignment of the LC molecules.
