Abstract
A light emitting device, a method of fabricating a light emitting device and a method of controlling light emission. The light emitting device includes a plasmonic structure. The plasmonic structure is configured to have a plurality of localized surface plasmon resonances. The light emitting device also includes a broadband light emitting layer having an emission spectrum substantially overlapping wavelengths of the localized surface plasmon resonances. A spacer layer is disposed between the plasmonic structure and the broadband light emitting layer. A color of light emitted by the broadband light emitting layer is tunable by the localized surface plasmon resonances of the plasmonic structure.
