The dependence of the enhancement effect on the element concentration in the sample matrix has been investigated by energy dispersive X-ray fluorescence analysis. The values of the enhancement effect factors for La2O3-Pr6O11-Sm2O3, La2O3-Sb-Eu2O3, and La2O3-Sm2O3-Gd2O3 at 59.5 keV incident photon energy have been measured.
