## Abstract The fluorescence quenching under high excitation intensities has been studied in anthracene crystals. The singlet–singlet annihilation constant of (1 ± 0.5) × 10^−8^ cm^3^ s^−1^ is calculated from the quenching of fluorescence induced by a nitrogen 16 ns pulse laser (λ = 3371 Å). The ma
Luminescence decay curves from undoped crystals of CsMnCla, RbMnCls, RbzMnCl4 and CsMnBrs fit kinetics derived for processes with first-and second-order components. The second-order effects which depend directly on excitation intensity are attributed to exciton annihilation. In contrast, decay curve
