Surface-plasmon-pumped light emitting devices

An OLED device comprising:

• a plurality of individually-addressable OLED pixels disposed over a substrate, comprising:
• a first pixel comprising:
• a first electrode disposed over the substrate;
• a first emissive stack disposed over the first electrode, the first emissive stack comprising a first organic emissive material;
• a second electrode disposed over the emissive stack;
• and
• a first emissive outcoupling layer disposed over the second electrode or between the first electrode and the substrate, the first emissive outcoupling layer comprising a second emissive material comprising a material selected from a group consisting of:
• a quantum dot, perovskite nanocrystals, a metalorganic framework, a covalent-organic framework, a thermally activated delayed fluorescence (TADF) emitter, a fluorescent emitter, and a phosphorescent organic emitter,
• wherein the first electrode or the second electrode non-radiatively transfers energy from the first organic emissive material to the first emissive outcoupling layer;
• and
• a second pixel comprising:
• a third electrode disposed over the substrate;
• a second emissive stack disposed over the third electrode, the second emissive stack comprising the first organic emissive material;
• a fourth electrode disposed over the emissive stack;
• and
• a second emissive outcoupling layer disposed over the fourth electrode or between the third electrode and the substrate, the second emissive outcoupling layer comprising a third emissive material, different from the second emissive material, the third emissive material comprising a material selected from a group consisting of:
• a quantum dot, perovskite nanocrystals, a metalorganic framework, a covalent-organic framework, a thermally activated delayed fluorescence (TADF) emitter, a fluorescent emitter, a phosphorescent organic emitter, a material having a Stokes shift of not more than 20 nm, a downconverting material that converts a high-energy excitation state to a lower-energy wavelength emission, a molecule that changes the orientation of one or more transition dipole moments (TDMs) upon excitation of the molecule, or a combination thereof.
