Abstract ZnO nanopowders with hexagonal wurtzite structure were synthesized by hydrothermal method with different concentrations of Fe. X-ray diffraction (XRD), scanning electron microscopy (SEM), Raman spectroscopy, X-ray photoelectron spectroscopy The morphology, structure and optical properties of the samples were tested and characterized by XPS and (photoluminescence) PL spectra.The results show that the crystal structure of wurtzite ZnO does not change with the increase of Fe doping concentration, and Fe ions do not change into ZnO lattice instead of Zn ions. At the same time, the uniformity of flower-like ZnO nanorods deteriorates, Fe doping A small number of single nanorods with smaller sizes appeared in the hetero-ZnO nanorods.The PL spectrum shows that as the Fe doping concentration increases, the UV luminescence peak of the sample does not change significantly, and the intensity of the luminescence peak decreases first and then increases, indicating that the defect of the sample first decreases and then increases.When the concentration of Fe doping is 1.5%, the prepared ZnO flower-like nanorods have a relatively low visible luminescence peak, which has a small defect.

Fe掺杂ZnO纳米棒的水热合成及光学性能

摘要 采用不同Fe浓度的水热法合成了六方纤锌矿结构的ZnO纳米粉体。X射线衍射（XRD）、扫描电子显微镜（SEM）、拉曼光谱、X射线光电子能谱对样品的形貌、结构和光学性质进行了XPS和（光致发光）PL光谱测试和表征。结果表明：纤锌矿ZnO的晶体结构不随Fe掺杂浓度的增加而变化，Fe离子不转变为ZnO晶格而不是Zn离子。同时，花状ZnO纳米棒的均匀性变差，Fe掺杂在异质ZnO纳米棒中出现了少量尺寸较小的单根纳米棒。PL光谱表明，随着Fe掺杂浓度的增加，
