In this study, the experimental characterization of cerium oxide (CeO2) powders doped with Ag at various amounts of 1, 2, 3, and 4 at.% was done using X-ray diffraction (XRD), differential thermal analysis (DTA), thermogravimetric analysis (TGA), Fourier transform infrared (FTIR) spectroscopy, Raman analysis, scanning electron microscopy (SEM), energy dispersive X-ray (EDX), and vibrating sample magnetometry (VSM). The formation of the single phase of CeO2, having the cubic crystal structure, for all samples was observed. The phase structure was not affected by the as-used Ag contents. The addition of Ag caused an increase in the lattice parameter and a decrease in the crystallinity. In addition to these, non-gradual changes in the crystallite size were observed. The thermal stability for each sample was seen for each sample until 1000 °C. The morphology composed of the microparticles was observed. The magnetization and magnetic susceptibility values were affected by the amount of Ag dopant.

Ag掺杂CeO 2的合成与表征

在这项研究中,使用X射线衍射(XRD),差热分析(​​DTA)对掺有各种浓度分别为1,2、3和4 at。%的Ag的氧化铈(CeO 2)粉末进行了实验表征,热重分析(TGA),傅立叶变换红外(FTIR)光谱,拉曼分析,扫描电子显微镜(SEM),能量色散X射线(EDX)和振动样品磁强(VSM)。CeO 2单相的形成对于所有样品,均具有立方晶体结构。相结构不受所用Ag含量的影响。Ag的添加引起晶格参数的增加和结晶度的降低。除此之外,观察到微晶尺寸的非逐渐变化。在1000℃之前观察到每个样品的每个样品的热稳定性。观察到由微粒组成的形态。磁化率和磁化率值受Ag掺杂量的影响。
