Abstract: 

The effect of Li2O  and ZnO  content and Eu3+ ion concentration in the glass composition on the decay of luminescence was investigated in phosphate glasses of composition P2O5—Li2O—ZnO  . The emission was excited by high-current electron beam of nanosecond duration with an electron energy of 200  eV. It was found that in the range of 0.5—3  wt.% Eu2O3 the decay time depends weakly on europium ion concentration. The increase of ZnO  (with parallel reduction of Li2O  ) leads to a shortening the decay time of luminescence in the bands at 592 and 614  nm of 2.1 to 1.5  ms. This is due to the symmetry reduction of the Eu3+ ion environment. The rise of luminescence signal with duration of some microseconds in the kinetics of the luminescence peak at 614  nm was observed.
