✦ Synopsis

The magnetic field dependence of host as well as of guest delayed fluorescence in tetracenedoped anthracene crystals was measured. The positions of the high field level-crossing resonances for heterofusion indicate that tetracame molecules enter the anthracene lattice substitutionally. The changes in intensity of the resonance peaks with tetracene concentration indicate that the tetracene-anthracene triplet e&ton annihilation gives rise to both tetracene and anthracene delayed fluorescence.
