Kopsavilkums

The transient absorption spectra and relaxation kinetics under pulse electron beam excitation in ZnWO₄ and ZnWO₄-Fe, as well as luminescence spectra and decay kinetics, were studied. It is shown that a fraction of transient absorption is due to luminescence center excited state. The energy transfer from intrinsic excitations to the defect or impurity states is not efficient. The role of Fe-impurities in the decay process is discussed.
