The concentration dependence curves of several , , and activated phosphors for different excitations have been studied. The optimum activator concentration was found to be a function of the number of excited activator ions as well as the exciting wavelength. For exciting radiation having a high absorption coefficient, the optimum activator concentration of a given phosphor shifted to low concentration. The concentration dependence curves of and phosphors under cathode‐ray excitation are almost identical to the curves obtained with host photoexcitation.
