Abstract
In this paper, we study the energy transferred between a pair of acceptor-donor molecules near a graphene-coated metallic nanoparticle by using the Laplace equation in a quasi-static approximation. After performing theoretical calculations and computer simulations, the influence of the system parameters such as the refractive index of the environment and the contribution of multipolar in different modes on the energy exchanged between the pair of molecules and nanoparticles is analyzed and investigated. The results show that graphene coating enhances plasmon-plasmas coupling in the nanostructure, consequently, enhances the energy transferred between the two molecules and the nanoscale. Therefore, this structure could be used as a new route designing nano-based biosensors.
