In this work, new compositions of SrMg(SnZr)O 0.00 ≤ ≤ 0.06 ceramics are designed and synthesized by the conventional solid-state route. The influence of Zr doping on the phase, microstructural, optical, and dielectric properties is thoroughly investigated. The peaks (0 0 4) and (1 1 0) are observed to shift toward lower 2θ values, due to the variation of the ionic radius between Zr and Sn. X-ray diffraction patterns reveal the orthorhombic structure with the space group . Scanning electron microscopy images reveal the presence of pores and particles with a high degree of agglomeration. The functional groups and modes of vibration are determined by Fourier transform infrared spectroscopy of the prepared metal oxide samples. The existence of green emission of all the synthesized samples around 554.91 nm is identified by photoluminescence spectroscopy. The dielectric properties of the fabricated samples are measured by using an impedance analyzer. The values of the tangent loss and relative permittivity are found to decrease with increasing frequency.
在本工作中，通过传统的固态路线设计并合成了SrMg(SnZr)O（0.00≤≤0.06）陶瓷的新成分。深入研究了Zr掺杂对相、微观结构、光学和介电性能的影响。由于Zr和Sn之间离子半径的变化，观察到(0 0 4)和(1 1 0)峰向较低的2θ值移动。X射线衍射图谱揭示了具有空间群的正交结构。扫描电子显微镜图像显示存在孔隙和高度团聚的颗粒。通过对制备的金属氧化物样品进行傅里叶变换红外光谱测定其官能团和振动模式。通过光致发光光谱确定了所有合成样品在554.91nm左右存在绿色发射。使用阻抗分析仪测量了所制备样品的介电性能。发现损耗角正切值和相对介电常数随频率增加而降低。
