  • Long-persistent luminescent composition, long-persistent luminescent device and wavelength control method
    Patent number: 11505739
    Abstract: An organic long-persistent luminescent composition containing a first organic compound, a second organic compound and a third organic compound and satisfying the following expression (1) is a long-persistent luminescent material that facilitates emission color control. ES1(A) represents a lowest excited singlet energy level of emission from the first organic compound and the second organic compound, ES1(B) represents a lowest excited singlet energy level of the third organic compound. ES1(B)?ES1(A)?0.

  • PERSISTENT LUMINESCENCE EMITTER
    Publication number: 20220243122
    Abstract: Disclosed is a persistent luminescence emitter containing at least 70 mol % of an electron donor molecule and less than 30 mol % of an electron acceptor molecule wherein an electron transfer occurs from the electron donor molecule to the electron acceptor molecule by photo-irradiation of the persistent luminescence emitter, and after photo-irradiation of the persistent luminescence emitter stops, emission intensity decays non-exponentially.

  • PERSISTENT LUMINESCENCE EMITTER
    Publication number: 20220246861
    Abstract: Disclosed is a persistent luminescence emitter containing an electron donor molecule and an electron acceptor molecule having a LUMO level of lower than ?3.5 eV, wherein emission intensity increases by temperature rise after photo-irradiation of the persistent luminescence emitter stops.
