Body-of-Revolution Finite-Element Model of Plasmon-Enhanced Fluorescence
Luke C. Ugwuoke, Farooq Kyeyune, Tjaart P. J. Krüger
Plasmon-enhanced fluorescence (PEF) is one of the most widely investigated optical phenomena in hybrid systems of emitters and plasmonic nanoantennas, with applications ranging fro…
Electrostatic dipole polarizability and plasmon resonances of multilayer nanoshells
L. C. Ugwuoke, M. S. Tame
We propose a generalized formula for calculating the dipole polarizability of spherical multilayer nanoshells (MNSs) within the long-wavelength approximation (LWA). Given a MNS wit…
Plasmon resonances in multilayer Fanoshells
Luke C. Ugwuoke, Tjaart P. J. Krüger
We develop a theoretical framework, based on a multipole, quasi-static approach, for the prediction of the localized surface plasmon resonances in Fanoshells formed via geometrical…
Plasmonic Quantum Yield Enhancement of a Single Molecule Near a Nanoegg
Luke C. Ugwuoke, Tomáš Mančal, Tjaart P. J. Krüger
We investigate the impact of the dipole-active modes formed via the mode-mixing of the dipole mode with higher-order surface plasmon modes of a nanoegg on the radiative decay rate…
Localized Surface Plasmon Resonances of Simple Tunable Plasmonic Nanostructures
Luke C. Ugwuoke, Tomáš Mančal, Tjaart P. J. Krüger
We derive and present systematic relationships between the analytical formulas for calculation of the localized surface plasmon resonances (LSPR) of some plasmonic nano-structures…
