Title: An organic light emitting device
Inventor: RICHARD FRIEND
IPC: H01L51/52
Filed: 2019-12-10
Abstract: An organic light emitting device comprises an anode, a cathode and an emissive layer comprising first and second materials which are different organic semiconductor compounds. The second material has a spin doublet ground state, and the lowest spin singlet excitation energy and lowest spin triplet excitation energy of the first material are greater than the lowest spin doublet excitation energy of the second material. In use, energy is transferred from the singlet and triplet excited states of the first material to excited doublet states in the second material, which emits fluorescent light when transitioning from the doublet excited state to the ground state. The first material is preferably a thermally activated delayed fluorescence (TADF) material, such as PXZ-DPS, CzDBA or 4CzIPN. The doublet emitter may be a stable organic radical incorporating tris(2,4,6-trichlorophenyl)methyl (TTM), such as TTM-1CZ, TTM-3NCZ, TTM-3PCZ, TTM-TPA, TTM-PPTA or TTM-PyID. Both first and second materials may be doped into a third material, such as CBP, as a host material.
