Abstract The properties of Ce-doped ZnO (CZO) thin films synthesized through sol-gel dip coating processing were evaluated. Five thin films were synthesized by increasing Ce percentage between 1–5 at. wt.%. The XRD study put forward that Ce doped ZnO displayed hexagonal wurtzite ZnO structure and Ce ions are embedded in the ZnO lattice successfully. Results showed that the crystallite size decreased, as the percentage of Ce in the ZnO increased. The lattice volume of the thin film was distorted in the presence of Ce. Broadening and shrinking of the band gap took place under different Ce doping concentrations due to generation of defects and appearance of secondary phase. All thin film has shown antibacterial activity.

调整 ZnO 薄膜的光学和抗菌特性：Ce 含量的作用

摘要 评价了溶胶-凝胶浸涂工艺合成的Ce掺杂ZnO（CZO）薄膜的性能。通过在 1-5 at 之间增加 Ce 百分比合成了五种薄膜。重量百分比。XRD研究表明，Ce掺杂的ZnO呈现六方纤锌矿ZnO结构，Ce离子成功嵌入ZnO晶格中。结果表明，随着 ZnO 中 Ce 百分比的增加，晶粒尺寸减小。在 Ce 的存在下，薄膜的晶格体积发生畸变。由于缺陷的产生和二次相的出现，带隙在不同的 Ce 掺杂浓度下发生变宽和收缩。所有薄膜都显示出抗菌活性。
