摘要： An organic light-emitting device containing a compound having a lone electron pair and a π electron orbital, the compound emitting fluorescent light by such a mechanism that when at least apart of electrons constituting the lone electron pair is excited to an excited triplet state 3nπ* through nπ* transition, the part of electrons undergoes inverse intersystem crossing from the excited triplet state 3nπ* to an excited singlet state 1nπ*, and returns from the excited singlet state 1nπ* to the ground state, at which the fluorescent light is emitted. The organic light-emitting device has a high light emission efficiency.

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.
