Abstract

Time-correlated photon counting technique has been applied to elucidate exciton dynamics in pyrene crystals. Transient free-exciton luminescence is observed at high temperatures as well as free-exciton luminescence associated with thefmalized free excitons. The self-trapping barrier height has been estimated to be 262 cm from the temperature dependence of the decay rate of the transient free-exciton luminescence. Also, luminescence due to unrelaxed self-trapped excitons is found at reduced temperature below the phase transition point, 120 K.
