在 80°C 的温度下，在玻璃基板上成功地制备了 Ni 掺杂 ZnO 棒阵列。通过掺杂剂的浓度可以很容易地很好地控制棒的密度、直径和长度，并且掺杂剂Ni离子被纳入ZnO晶体的纤锌矿结构中。棒阵列的室温光致发光光谱在 410 nm 处显示出强发射带，并且在 ZnO 棒阵列中掺杂 Ni 后，ZnO 结构中的氧缺陷显着减少。在室温下测量的磁化强度的场依赖性表现出明显的铁磁特性。
Ni-doped ZnO rod arrays were successfully prepared on glass substrate from the aqueous solution at a temperature of 80 °C. The densities, diameters, and lengths of the rods can easily be well controlled through the concentrations of dopants, and the dopant Ni ions were incorporated into the wurtzite-structure of ZnO crystal. Room temperature photoluminescence spectrum of rod arrays show a strong emission band at 410 nm, and the oxygen deficiencies in ZnO structures were significantly reduced with Ni doped in ZnO rod arrays. The field dependence of magnetization measured at room temperature exhibited the obvious ferromagnetic properties.
