Abstract

Double perovskites RBaFeTiO (R = La, Eu) were successfully synthesized using a solid state reaction route. Structural refinement analysis has been performed to investigate the details of the crystalline structure which was found to be a cubic double perovskite structure at room temperature (space group 3̄, No. 221). Crystallite size, lattice strain, density, and porosity parameters were also calculated. The morphology and the elemental composition were analyzed by scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX) and elemental mapping. FTIR and Raman scattering spectroscopy have been performed in order to study the vibrational modes and the various bond formations of the synthesized samples. The optical properties investigated by means of the optical absorbance measurements highlight that both materials present large band gap energies, and are thus potential candidates for various technological applications. The electrical behavior of these double perovskites was also studied by frequency-dependent dielectric measurements and impedance spectroscopy. The electrical conduction follows Jonscher's power law and the conduction mechanisms are identified.

摘要

采用固态反应路线成功合成了双钙钛矿RBaFeTiO（R = La，Eu）。进行了结构精修分析以研究晶体结构的细节，发现其在室温下为立方双钙钛矿结构（空间群3̄，编号221）。还计算了微晶尺寸、晶格应变、密度和孔隙率参数。通过扫描电子显微镜（SEM）、能量色散X射线光谱（EDX）和元素映射分析了形态和元素组成。为了研究合成样品的振动模式和各种键的形成，进行了傅里叶变换红外光谱（FTIR）和拉曼散射光谱分析。通过光吸收测量研究的光学性质表明，这两种材料都具有较大的带隙能量，因此是各种技术应用的潜在候选材料。还通过频率相关的介电测量和阻抗谱研究了这些双钙钛矿的电学行为。导电遵循琼舍尔幂律并确定了导电机制。
