- Nanoscale Tailored Plasmonic Material for Optimum Broadband Solar Harvesting
Éadaoin McClean-Ilten and Dominic Zerulla
Article first published online: 30 NOV 2015 | DOI: 10.1002/adom.201500513
Plasmonically enhanced solar cell device efficiency is increased using a fundamental structural re-design of surface plasmon coupling materials. Through an analytically defined nanoscale structure, optimum momentum matching is achieved over entire, specifically addressed wavelength ranges. The ability of the system to tailor a function defined topography for the optimum enhancement through plasmonics is demonstrated.

Near-field coupling of bright and dark resonances has been extensively observed in plasmonic and metamaterial lattices, where the coupling usually occurs by radiative modes. Here, an anisotropic inductive coupling is experimentally studied in a metamolecule system and a coupling dependent suppression and excitation of bright mode is demonstrated.

Optical gain spectroscopy of colloidal nanocrystals is performed using a tunable open access microcavity with an ultra-small mode volume. By tuning the cavity mode energy across the nanocrystal ensemble emission band while performing lasing threshold measurements, information on the material gain characteristics can be extracted.
- Simple Planar Indium-Tin-Oxide-Free Organic Light-Emitting Devices with Nearly 39% External Quantum Efficiency

A simple planar indium-tin-oxide-free organic light-emitting device (OLED) with a significantly enhanced external quantum efficiency of nearly 39% is reported. By inserting a high-index layer below the low-index transparent conducting polymer electrode, most optical benefits of the low-index electrode are retained, yet the radiation into the substrate is more convergent within the escape cone for direct optical out-coupling.
- Zero-Reflectance Metafilms for Optimal Plasmonic Sensing

Zero-reflectance metafilms are demonstrated to be optimal plasmonic sensors. Complete annihilation of the reflectance (R) of a highly reflective surface such as Si can be achieved with an ultrathin layer of Au nanoparticles. Such zero-reflectance metafilms show much superior plasmonic sensing performance than those of nonzero reflectance films.
