A picosecond laser system has been employed to study the kmetics of singlet evciton energy transfer m p-terphenyl single crystals doped with tetracene over the temperature range 77-300 K. First-order kinetics prevail and exciton migration from host to guest is controlled by thermal activation over a

## Abstract The fluorescence quenching under high excitation intensities has been studied in anthracene crystals. The singlet–singlet annihilation constant of (1 Β± 0.5) Γ— 10^βˆ’8^ cm^3^ s^βˆ’1^ is calculated from the quenching of fluorescence induced by a nitrogen 16 ns pulse laser (Ξ» = 3371 Γ…). The ma

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 i

Changes in spectral frequencies and intensities recorded at low temperatures (4 to 40 K), as well as measurements of prompt-fluorescence lifetimes, of annealed and deformed high-purity single crystals of anthracene reveal that traps l013ed nt ca. 300 cm-' and 1500 cm-' below the Sr level may be ascr
