Abstract

Herein, the structural, optical, and magnetic properties of Y0.85La0.15FexAlyO3: (x; y) where x = 1; y = 0, x = 0.975; y = 0.025, x = 0.95; y = 0.05, and x = 0.9; y = 0.1 nanomaterials obtained from sol–gel method are reported. The X‐ray powder diffraction (XRD) for the structural characterization, scanning electron microscopy for crystallite size estimation, ultraviolet–visible absorption for optical studies, and vibrating‐sample magnetometer for magnetic studies are used in this investigation. An increase of orthorhombic crystal structure with an increase of Al content in the sample is observed from XRD studies. The existence of all the elements present in the samples is observed from energy‐dispersive X‐ray spectroscopy. The optical bandgap increases from 2.04 to 2.10 eV with an increase of Al concentration from 0 to 0.05. The observed magnetization value is 3.14 emu g−1 for y = 0.05, which is higher than y = 0 (2.11 emu g−1) and y = 0.024 (2.58 emu g−1). In summary, the obtained result (x = 0.95; y = 0.05) can be useful for different magnetic‐based applications.

三价离子（La+3 和 Al+3）掺杂和共掺杂对氧化亚铁纳米材料的协同影响

本文报告了溶胶-凝胶法获得的 Y0.85La0.15FexAlyO3: (x; y) （其中 x = 1; y = 0、x = 0.975; y = 0.025、x = 0.95; y = 0.05 和 x = 0.9; y = 0.1）纳米材料的结构、光学和磁学特性。本研究采用了 X 射线粉末衍射（XRD）进行结构表征，扫描电子显微镜进行晶粒尺寸估算，紫外可见吸收进行光学研究，振动样品磁力计进行磁性研究。从 XRD 研究中可以观察到，随着样品中铝含量的增加，正方晶体结构也在增加。从能量色散 X 射线光谱中可以观察到样品中所有元素的存在。随着铝浓度从 0 增加到 0.05，光带隙从 2.04 eV 增加到 2.10 eV。y = 0.05 时的磁化值为 3.14 emu g-1，高于 y = 0（2.11 emu g-1）和 y = 0.024（2.58 emu g-1）。总之，所得结果（x = 0.95; y = 0.05）可用于不同的磁性应用。
