Abstract In this research work, we have studied the effect of substitution of Sr on the structural, morphological and impedance spectroscopic properties of Zr1−xSrxTiO4 (x = 0, 0.05, 0.10, 0.15 and 0.2), synthesized using sol-gel auto-combustion technique. The X-ray diffraction confirmed the orthorhombic phase. The Fourier transform infrared spectroscopy spectra confirmed that no organic content was present in the sample. Field emission scanning electron microscopic analysis reveals that the particle size reduces from 125 nm to 15 nm. Energy dispersive X-ray technique confirmed the presence of Zr, Ti, Sr and O in the matrix. Dielectric properties are measured at room temperature in the frequency range of 20 Hz to 20 MHz by using the impedance analyzer. Dielectric parameters have been studied by using Koop's theory and Maxwell-Wagner's Model. AC conductivity increases with the increase in frequency and with increasing Sr contents. The impedance plot shows the dominance of grain boundary resistance. Dielectric relaxation process has been studied using Modulus plot.

摘要 在这项研究工作中，我们研究了 Sr 的取代对 Zr1−xSrxTiO4 (x = 0, 0.05, 0.10, 0.15 和 0.2) 的结构、形态和阻抗光谱特性的影响，使用溶胶-凝胶自动燃烧合成技术。X 射线衍射证实了正交相。傅里叶变换红外光谱证实样品中不存在有机成分。场发射扫描电子显微镜分析表明，粒径从 125 nm 减小到 15 nm。能量色散 X 射线技术证实了基体中存在 Zr、Ti、Sr 和 O。介电特性是在室温下使用阻抗分析仪在 20 Hz 至 20 MHz 的频率范围内测量的。使用 Koop 理论和 Maxwell-Wagner' 研究了介电参数 型号。AC 电导率随着频率的增加和 Sr 含量的增加而增加。阻抗图显示了晶界电阻的优势。已经使用模量图研究了介电弛豫过程。
