Nature of lasting luminescence of rubrene in solution

Conclusions

  1. 1.

    The T2→T1 fluorescence of rubrene is absent in liquid solutions due to the rapid internal conversion between the T2 and T1 triplet states of the molecule.

     
  2. 2.

    During sensitized excitation a delayed fluorescence of rubrene arises due to a crossed annihilation of the molecules, that of the energy donor and rubrene in the triplet state. Its efficiency is considerably higher than when two rubrene triplet molecules collide.
