The structural, optical and magnetic properties of nanorod structured polycrystalline Zn1−xMnxO3 films $$\left( {0 \le x \le 0.1} \right)$$ grown on glass substrate using Sol–Gel technique have been investigated. X-ray diffraction (XRD) analysis reveals average grain sizes from 15 to 25 nm. There was gradual increase in both the crystallite size and lattice constant with increase in Mn content up to 0.2%, and then decrease of them with further increase in Mn content. The same result has been confirmed by SEM experiments. It has been revealed that the band gap value of Zn1−xMnxO film decreases from 3.34 to 2.97 eV with an increase in Mn concentration from x = 0.0 to 0.1, which is in agreement with the previously reported results. The studies of the magnetization and magnetic resonance of Zn1−xMnxO films revealed the presence of the paramagnetic state without any magnetic ordering.

使用溶胶-凝胶技术合成的纳米棒状多晶 Zn1-xMnxO 薄膜的结构、光学和磁性表征

已经研究了使用溶胶-凝胶技术在玻璃基板上生长的纳米棒结构多晶 Zn1−xMnxO3 薄膜 $$\left( {0 \le x \le 0.1} \right)$$ 的结构、光学和磁性能。X 射线衍射 (XRD) 分析显示平均晶粒尺寸为 15 至 25 nm。随着Mn含量增加至0.2%，晶粒尺寸和晶格常数逐渐增加，然后随着Mn含量的进一步增加而减小。SEM 实验也证实了相同的结果。研究表明，随着 Mn 浓度从 x = 0.0 增加到 0.1，Zn1-xMnxO 薄膜的带隙值从 3.34 eV 降低到 2.97 eV，这与之前报道的结果一致。
