摘要：我们通过 X 射线吸收精细结构测量研究了空气中退火对 BaMgAl10O17 中掺杂铕的影响。我们通过在超过 500°C 的空气中退火来确定掺杂二价铕的氧化。铕和周围氧原子之间的原子间距离因氧化而被压缩。铕的氧化过程似乎是由氧扩散到 BaMgAl10O17 中决定的。
Abstract— We studied the influence of annealing in air on doped europium in BaMgAl10O17 by performing x‐ray absorption fine‐structure measurements. We determined the oxidation of doped divalent europium by annealing in air at over 500°C. The interatomic distance between the europium and the surrounding oxygen atoms was compressed by oxidation. It also appears that the oxidation process of europium is determined by the diffusion of oxygen into BaMgAl10O17.
