Abstract :
The magnetic field effect (MFE) on the fluorescence of amorphous and polycrystalline rubrene films has been investigated both experimentally and theoretically. This MFE is known to be due to the annihilation of triplet excitons. The specific features of MFE in these two films turn out to be different. A theoretical analysis has been made within a simple model which takes into account the spin lattice relaxation. The MFE in rubrene films is shown to be strongly affected by the magnetic field dependent spin lattice relaxation.
