Abstract: Light-emitting devices having an emitting layer containing a light-emitting organic or organometallic material and a nanostructure, the nanostructure having strong local electric fields at visible electromagnetic wavelengths that spectrally and spatially overlap with the light-emitting material. The spectral and spatial overlap of the electric fields of the nanostructure with the light emitting material uses high LDOS provided by the nanostructures to enable excited triplet electronic states in the material to emit light faster than without the nanostructure. This faster light emission from triplet-excited states leads to more stable emission from the light emitting material because it prevents buildup of triplet-excited states, which ordinarily can lead to quenching of light emission from the light emitting material. Among the many different possibilities contemplated, the nanostructure may advantageously be made of a dielectric material or a plasmonic metal material, such as SiO2, TiO2, ZnO, Al or Ag.
