摘要：

The luminescence spectra, rise and decay kinetics and the yield of luminescence in undoped PbWO4 crystals were studied after pulsed electron beam irradiation. The luminescence intensity rise observed after irradiation pulse showed two mechanisms-excitonic relaxation and electron-hole recombination-were involved in the formation of the excited states of the blue luminescence centers. It is proposed that the excited states of WO3 and WO42- luminescence centers were formed from some intermediate metastable state. (C) 1998 Elsevier Science Ltd. All rights reserved.
