In this study the enhancement effect depending on the changing of the sample of the matrix element has been investigated using energy dispersive X-ray fluorescence analysis. The present measured values of the enhancement effect factors for eight series (La2O3-Sm2O3, La2O3-Eu2O3, La2O3-Gd2O3, La2O3-Tb4O7, La2O3-Dy2O3, La2O3-Ho2O3, La2O3-Er2O3 and La2O3-Tm2O3) at 59.5 keV incident photon energy have been studied. It has been observed that changing of the matrix element influence the enhancement effect.
