Kinetics of the luminescence decay of impurity Fe2+ centers in ZnSe upon excitation by an electron beam

It is measured the kinetics of the luminescence of Fe2+ in ZnSe at liquid nitrogen temperature at excitation by short pulse of accelerated electrons. An explanation of the observed dependence is presented, which is based on Auger effect of quenching the excited state of the Fe2+ ion by free electrons of the electric current in the volume of the sample.
