Abstract Undoped, Na-doped, and Na-F codoped ZnO films were synthesized using sol-gel method. Na+ and F+ ions were used as two different dopants that yielded a synergistic doping effect. This effect was measurable using XRD, accompanied by a redshift in the optical bandgap from 3.284 to 3.261 eV in ZnO, ZnO-F, and ZnO-Na-F thin films, respectively. We then studied the resulting photoluminescent changes, which were attributed to O-related defects. Ferromagnetism measurements revealed that magnetic orderings decreased significantly with F doping. However, increased Na doping enhanced the oxygen-vacancy mediated ferromagnetic state.

Na&F掺杂对溶胶-凝胶法合成ZnO薄膜微观结构、光学和磁性的影响

摘要 采用溶胶-凝胶法合成了未掺杂、Na 掺杂和Na-F 共掺杂的ZnO 薄膜。Na+ 和 F+ 离子被用作两种不同的掺杂剂，产生了协同的掺杂效果。这种效应可以使用 XRD 测量，伴随着 ZnO、ZnO-F 和 ZnO-Na-F 薄膜的光学带隙从 3.284 eV 红移到 3.261 eV。然后我们研究了由此产生的光致发光变化，这归因于与 O 相关的缺陷。铁磁性测量表明，随着 F 掺杂，磁序显着降低。然而，增加的 Na 掺杂增强了氧空位介导的铁磁状态。
