采用共沉淀法制备了Ni掺杂in2o3纳米晶，并在无磁场和12t磁场下进行了煅烧。x射线衍射和透射电镜图像显示，纳米晶体高度结晶，未检测到二次相。结果表明，外加磁场处理对纳米晶体的生长行为有影响。在（In1−xNix）2O3（x=0.05和0.12）纳米晶体中观察到室温铁磁性。镍掺杂浓度和外加磁场处理可控制纳米晶体的铁磁性。研究了掺杂镍的纳米晶体的光致发光性能。
Ni doped In2O3nanocrystals were prepared by a coprecipitation method, and calcined in the absence of a magnetic field or in 12 T magnetic field. X-ray diffraction and transmission electron microscopy images reveal that the nanocrystals were highly crystalline and no secondary phase was detected. It is found that growth behavior of the nanocrystals was affected by the external magnetic field treatment. Room temperature ferromagnetism was observed in (In1−xNix)2O3(x=0.05 and 0.12) nanocrystals. The ferromagnetism of the nanocrystals was controlled by Ni doping concentration and the external magnetic field treatment. The photoluminescence properties of the Ni doped In2O3nanocrystals were also investigated.
