— The dependence of the cathodoluminescence (CL) efficiencies of Y 2 O 2 S: Eu, Y 2 O 2 S: Pr, Y 2 O 3 :Eu, and (Cd, Zn)S: Cu, Al on the width of high‐current‐density excitation pulses was found to be dependent upon the persistence time of the phosphors. This dependence was explained in terms of phosphor saturation.
