  • HIGHLY EFFICIENT OLED DEVICES WITH VERY SHORT DECAY TIMES
    Publication number: 20240107873
    Abstract: The present invention relates to organic light-emitting devices comprising (a) an anode, (i) a cathode, and (e) an emitting layer between the anode and cathode, comprising 2 to 40% by weight of a triplet emitter X having a difference of the singlet energy (ES1(X)) and the triplet energy (ET1(X)) of less than or equal to 0.4 eV [?(ES1(X)) ?(ET1(X))?0.4 eV], 0.05 to 5.0% by weight of a fluorescent emitter Y and 55 to 97.95% by weight of a host compound(s), wherein the amount of the triplet emitter X, the fluorescent emitter Y and the host compound(s) adds up to a total of 100% by weight and the singlet energy of the triplet emitter X(ES1(X)) is greater than the singlet energy of the fluorescent emitter Y(ES1(Y)) [(ES1(X))>ES1(Y)].

  • Highly efficient OLED devices with very short decay times
    Patent number: 11075346
    Abstract: The present invention relates to organic light-emitting devices comprising (a) an anode, (i) a cathode, and (e) an emitting layer between the anode and cathode, comprising 2 to 40% by weight of a luminescent organometallic complex X having a difference of the singlet energy (ES1(X)) and the triplet energy (ET1(X)) of of ?0.3 eV [?(ES1(X))?(ET1(X))?0.3], 0.05 to 5.0% by weight of a fluorescent emitter Y and 55 to 97.95% by weight of a host compound(s), wherein the amount of the organometallic complex X, the fluorescent emitter Y and the host compound(s) adds up to a total of 100% by weight and the singlet energy of the luminescent organometallic complex X (ES1(X)) is greater than the singlet energy of the fluorescent emitter Y (ES1(Y)) [(ES1(X))>ES1(Y)].
