摘要

研究了金属离子（MI）掺杂对氧化锌纳米颗粒（ZnO-NPs）性能的影响。成功地合成了少量（1.7%）Al、Ag、Cu和Mn掺杂的ZnO-NPs。x射线衍射（XRD）证实了掺杂后六方纤锌矿结构的保留，没有观察到二次相。掺杂剂的离子半径与结构、振动和形态性质的一致变化之间存在明显的相关性。紫外可见光谱（UV-visible）显示，光学带隙明显变宽，从3.70 eV （ZnO）变为3.90 eV （al掺杂）、4.04 eV （Ag掺杂）、3.88 eV （Cu掺杂）和3.97 eV （Mn掺杂）。

The effect of low concentrations of selected metal ions (Al, Ag, Cu, Mn) on the properties of ZnO nanoparticles prepared by the co-precipitation technique

The effect of metal ion (MI) doping on the properties of zinc oxide nanoparticles (ZnO-NPs), was investigated. ZnO-NPs doped with a small amount (1.7 %) of Al, Ag, Cu, and Mn were successfully synthesized. X-ray diffraction (XRD) confirmed the retention of the hexagonal wurtzite structure after doping, with no secondary phases observed. A clear correlation was established between the ionic radii of the dopants and the consistent changes in the structural, vibrational and morphological properties. Ultraviolet–visible (UV–visible) spectroscopy showed a noticeable widening of the optical bandgap, shifting from 3.70 eV (ZnO) to 3.90 eV (Al-doping), 4.04 eV (Ag- doping), 3.88 eV (Cu- doping), and 3.97 eV (Mn- doping).
