Zn(0.97)Fe(0.03)O nanoparticles were synthesized by the sol-gel method. X-ray diffraction (XRD) and transmission electron microscope (TEM) analysis revealed that the samples had pure ZnO wurtzite structure and Fe ions were well incorporated into the ZnO crystal lattice. X-ray photoelectron spectroscopy (XPS) showed that both Fe(2+) and Fe(3+) existed in Zn(0.97)Fe(0.03)O. The result of x-ray absorption near-edge structure (XANES) further testified that Fe ions took the place of Zn sites in our samples. Magnetic measurements indicated that Zn(0.97)Fe(0.03)O was ferromagnetic at room temperature.
通过溶胶-凝胶法合成了Zn(0.97)Fe(0.03)O纳米颗粒。X射线衍射（XRD）和透射电子显微镜（TEM）分析表明，样品具有纯的ZnO纤锌矿结构，且Fe离子很好地掺入到ZnO晶格中。X射线光电子能谱（XPS）显示，Zn(0.97)Fe(0.03)O中同时存在Fe(2+)和Fe(3+)。X射线吸收近边结构（XANES）的结果进一步证明，在我们的样品中Fe离子取代了Zn位点。磁性测量表明，Zn(0.97)Fe(0.03)O在室温下具有铁磁性。
