The luminescence spectra, decay kinetics and yield of luminescence in undoped PbWO 3 crystals were studied after pulsed electron beam irradiation. The rise time of luminescence pulses shows that two mechanisms - excitonic and recombination - were involved in luminescence center excited state formation. It is proposed that excited states of WO 3 and WO 2- 4 luminescence centers were formed from some metastable state, possibly from Pb related excitation.
