Kopsavilkums

The luminescence spectra, rise and decay kinetics and the yield of luminescence in undoped PhWO₄ 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 WO₄^2- luminescence centers were formed from some intermediate metastable state.
