We examined the temperature dependence of the Eu valence in La 0.9Eu0.1Ni2(Si1-xGe x)2 by means of magnetic susceptibility measurements and X-ray absorption spectroscopy. It was found that the Eu ions are in the intermediate valence state for 0.2 < x < 0.8 and the Eu valence gradually varies with temperature. The results are compared with those of the concentrated EuNi2(Si1-yGey)2 compounds. The main factor in determining the Eu valence in both dilute and concentrated alloys is discussed.
