Abstract
We show that low-temperature fluorescence spectra of large high-quality single crystals are mainly composed of several, independent pairs of false origins. In analogy to the case of anthracene single crystals the series of emission bands can be interpreted in terms of exciton (Frenkel) emission from so-called X traps. Temperature dependent luminescence experiments support this interpretation.
