Figure 2From: Structural and electronic properties of Eu- and Pd-doped ZnO Total and partial DOS of the ZnO:Eu systems. Representing (a) ZnO:EuZn, (b) ZnO:EuI, (c) ZnO:EuZn + VO, (d) ZnO:EuZn + ZnI systems. The solid black lines and the red-shaded areas represent the total and Eu's partial 4f states, respectively. Also, energy is represented with respect to the Fermi level.Back to article page
