Uniform Lu₂O₃:Eu nanowire arrays were successfully prepared by the sol-gel process using anodic aluminum oxide (AAO) templates. The as-synthesized nanowires are homogeneous, highly ordered, and dense and have a uniform diameter of ~300 nm defined by the AAO templates. The X-ray diffraction and selected area electron diffraction results show that the Lu₂O₃:Eu nanowires have a polycrystalline cubic structure, and the crystallite size of the Lu₂O₃:Eu nanowires is confined by the AAO template. The nanowires within the AAO template showed good photoluminescence and X-ray-excited optical luminescence performances for Lu₂O₃:Eu. The emission peaks were attributed to the ⁵D₀ → ⁷F transitions of Eu (J = 0, 1, 2, 3).
通过溶胶 - 凝胶法利用阳极氧化铝（AAO）模板成功制备了均匀的Lu₂O₃:Eu纳米线阵列。所合成的纳米线均匀、高度有序且致密，具有由AAO模板定义的约300 nm的均匀直径。X射线衍射和选区电子衍射结果表明，Lu₂O₃:Eu纳米线具有多晶立方结构，并且Lu₂O₃:Eu纳米线的微晶尺寸受AAO模板限制。AAO模板内的纳米线对Lu₂O₃:Eu表现出良好的光致发光和X射线激发光致发光性能。发射峰归因于Eu的⁵D₀→⁷F跃迁（J = 0、1、2、3）。
