摘要
In this communication, the luminescence properties of ZnS luminophors are characterized. The effect of concentration quenching of the photo- and cathodoluminescence (PL, CL) is discussed. An appropriate mechanism of nonradiative recombination is proposed, and its efficiency is estimated. It is shown that the three-center Auger effect can be responsible for the cathodoluminescence saturation observed under increased current density.
