Resumo
Photoluminescence and structure properties of anodically prepared ZrO2 oxide films doped with Europium (III) ions were investigated. Microstructural analysis reveals that the predominant crystallographic structure is the monoclinic phase with small quantities of tetragonal and cubic phases. Important crystallite size and isotropic strain are observed for the monoclinic phase and they are related to the incorporation of Europium (III) ions inside the oxide matrix. The photoluminescence spectrum reveals a broad emission band in the range between 350-650nm related to the ZrO2. Emission lines corresponding to transitions from the lowest emitting 5D0 level of Eu(III) to several sublevels of the ground state level 7F0, 1, 2, 3, 4 were also observed.
