| 摘 要： | 利用溶胶凝胶法制备了Zn1-xFexO粉末.X射线衍射表明,所有样品都具有纤维锌矿结构,没有发现其他的衍射峰.紫外可见光吸收谱发现,随着掺杂量的增加样品的吸收边发生红移,能隙减小,表明Fe离子进入ZnO的晶格,替代了Zn离子.光致发光谱发现,在467,482nm出现了蓝光和近绿光.磁性测量表明,所有的样品都具有室温铁磁性,而且随着掺杂量的增加样品的饱和磁化强度增加. |
| 关 键 词： | 溶胶凝胶 紫外可见光吸收谱 光致发光谱 室温铁磁性 |

| Abstract: | Zn1-xFexO powders(x=0.02,0.05,0.07) have been prepared by a sol-gel process technique.X-ray diffraction results reveal that all samples are single ZnO wurtzite structure.As Fe concentration increase in the Zn1-xFexO,the absorption edges show red-shift.The decreasing band-gap energy with Fe concentration increasing confirmed that the Fe ions have entered into the ZnO crystal lattice.Photoluminescence measurements of Fe-doped samples illustrate blue emission and green emission centered at about 467,482 nm.The... |
