摘要： A nanoparticle conjugate includes a quantum dot (QD) and a thermally activated delayed fluorescence (TADF) molecule bound to the QD. In some instances, the TADF molecule can be directly bound to a surface of the QD. In other instances, the TADF molecule can be indirectly bound to the QD via an interaction with one or more capping ligands disposed on a surface of the QD. Nanoparticle conjugates described herein can be incorporated into emissive layers of electroluminescent light-emitting diode devices to yield electroluminescent quantum dot-containing light-emitting diode (QD-LED) devices.

摘要： An emissive layer of a top-emitting (TE) printed display comprises a combination of solution-processable nanocrystal quantum dots, thermally activated delayed fluorescent molecules, and a suitable host material along with both electron and hole charge transport materials sandwiched into a microcavity between a reflective bottom electrode and a transparent or semi-transparent top electrode. The electrodes may be reflective metals and the thickness of the emissive layers and charge transport layers may be tuned according to the required resonant wavelength along with the thickness of the top semi-transparent electrode to optimize the resonant condition and maximize the light output.
