We observed that (1) the luminescence spectra of α-perylene shifted by 440 cm-1as much as the change in the excitation photon energy, from 22100 cm-1(452.5 nm) to 22540 cm-1(443.7 nm), whereas the luminescence spectrum of pyrene shifted by 100 cm-1according as the excitation photon energy in an energy region from 26940 cm (371.2nm) to 26730cm-1(374.1nm), (2) for pyrene microcrystals the luminescence decay under resonant excitation increased as the excitation energy increased, (3) in both materials intense fsee-exciton luminescence was observed but self-trapped exciton luminescence was not.
