1. An organic light emitting device comprising:

  • an anode;

    a cathode;

    an emissive layer disposed between the anode and the cathode, the emissive layer further comprising;

    a singlet fission sensitizer, anda triplet emitter;

    wherein the singlet energy of the singlet fission sensitizer is equal to or greater than twice the triplet energy of the singlet fission sensitizer;

    the triplet energy of the triplet emitter is less than the triplet energy of the singlet fission sensitizer.
