Ten-Fold Enhancement of Photoluminescence – Nanoantennas Directing a Bright Future
Nanoantenna phosphors comprising of a periodic array of nanoparticles on the phosphor plate can tailor the spatial radiation pattern of the photoluminescence for smaller, lighter, and brighter solid-state lighting devices.
