The crystal structures of non-substituted and Mo-substituted neodymium tungstates are described in detail through neutron diffraction and high-resolution X-ray diffraction. Combined X-ray and neutron diffraction refinements and electron probe micro-analysis were employed to locate Mo atoms in the crystal structure of Nd6−yW1−zMozO12−δ (z = 0, 0.25), while X-ray absorption spectroscopy in the near-edge regions confirmed no changes in the oxidation states of Nd and W.

揭示 Nd5.8WO12-δ 和 Nd5.7W0.75Mo0.25O12-δ 混合离子电子导体的晶体结构

通过中子衍射和高分辨率 X 射线衍射详细描述了未取代和 Mo 取代的钨酸钕的晶体结构。结合 X 射线和中子衍射精修和电子探针显微分析，在 Nd6-yW1-zMozO12-δ (z = 0, 0.25) 的晶体结构中定位 Mo 原子，而 X 射线吸收光谱在近 -边缘区域证实 Nd 和 W 的氧化态没有变化。
