  • Patent number: 10700288
    Abstract: A light-emitting element that contains a fluorescent compound, which has high efficiency is provided. A light-emitting element in which the proportion of delayed fluorescence to the total light emitted from the light-emitting element is higher than that in a conventional light-emitting element is provided. Emission efficiency of the light-emitting element containing a fluorescent compound can be improved by increasing the probability of TTA caused by an organic compound in an EL layer, converting energy of triplet excitons, which does not contribute to light emission, into energy of singlet excitons, and making the fluorescent compound emit light by energy transfer of the singlet excitons.

  • Patent number: 10693098
    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.
