Pure and Nd-doped cerium oxides (CeO₂, CeNdO and CeNdO) nanoparticles (NPs) were synthesized using leaf extract. X-ray powder diffraction studies were confirmed that synthesized pure and Nd doped CeO₂ NPs and were exhibited cubic structure. FE-SEM image exhibited pure and Nd doped CeO₂ NPs have spherical structure and Nd doped CeO2 NPs small pores were formed in the surface. EDAX spectral analysis used to identify the elemental compositions. FT-IR spectra shows various functional groups and were identified for pure and Nd doped CeO₂ NPs. UV-Vis spectra, absorption edges were observed at 314 nm, 324 nm and 357 nm for pure and Nd doped CeO2 NPs respectively. PL spectral analysis, small shift observed for emission of the CeO2 NPs values as compared to that of the Nd doped CeO2 NPs emission values. The antimicrobial studies were performed against a set of Gram positive () and Gram negative () bacterial and fungal strain.
采用叶提取物合成了纯氧化铈（CeO₂）、掺钕氧化铈（CeNdO）和掺钕氧化铈（CeNdO）纳米粒子（NPs）。X 射线粉末衍射研究证实，所合成的纯氧化铈 NPs 和掺钕氧化铈 NPs 具有立方结构。FE-SEM 图像显示，纯氧化铈 NPs 和掺钕氧化铈 NPs 具有球形结构，而掺钕氧化铈 NPs 的表面形成了小孔。EDAX 能谱分析用于鉴定元素组成。FT-IR 光谱显示了各种官能团，并对纯氧化铈 NPs 和掺钕氧化铈 NPs 进行了鉴定。UV-Vis 光谱显示，纯氧化铈 NPs 的吸收边分别在 314nm、324nm 和 357nm 处，而掺钕氧化铈 NPs 的吸收边分别在 314nm、324nm 和 357nm 处。PL 光谱分析显示，与掺钕氧化铈 NPs 的发射值相比，CeO2 NPs 的发射值有较小的偏移。对一组革兰氏阳性（）和革兰氏阴性（）细菌和真菌菌株进行了抗菌研究。
