Abstract

The variation of structural and electric properties is investigated via different characterization methods for NaNbO₃ ceramics modified with Ta⁵⁺ ions. At room temperature, substitution of Ta⁵⁺ ions can effectively induce the phase coexistence and transition between orthorhombic antiferroelectric P and orthorhombic ferroelectric Q phase in NaNb_1-xTa_xO₃ ceramics. Thus, the ferroelectric and piezoelectric properties could be regulated with the maximum value of d₃₃ (~37.3) at x = 0.05. Besides, with increasing temperature, multiple phase transitions are demonstrated through dielectric, XRD, and in situ Raman results. Moreover, the temperature of various phase transitions gradually shifts toward lower temperature with increasing Ta⁵⁺ ions. Correspondingly, the modulation mechanism is also discussed based on the evolution of Raman vibration. This work is instructive for regulatable applications of NaNbO₃-based materials.

钽对无铅 NaNbO3 陶瓷结构和电气性能的影响

通过不同的表征方法研究了用 Ta5+ 离子修饰的 NaNbO3 陶瓷的结构和电特性变化。在室温下，Ta5+ 离子的取代能有效地诱导 NaNb1-xTaxO3 陶瓷中正交反铁电体 P 相和正交铁电体 Q 相的共存和转变。因此，在 x = 0.05 时，铁电和压电特性可以得到调节，d33 值达到最大（~37.3）。此外，随着温度的升高，介电、X 射线衍射和原位拉曼结果表明了多种相变。而且，随着 Ta5+ 离子的增加，各种相变的温度逐渐向低温方向移动。相应地，还根据拉曼振动的演变讨论了调制机制。这项工作对 NaNbO3 基材料的可调节应用具有指导意义。

期刊介绍： The Journal of Raman Spectroscopy is an international journal dedicated to the publication of original research at the cutting edge of all areas of science and technology related to Raman spectroscopy. The journal seeks to be the central forum for documenting the evolution of the broadly-defined field of Raman spectroscopy that includes an increasing number of rapidly developing techniques and an ever-widening array of interdisciplinary applications. Such topics include time-resolved, coherent and non-linear Raman spectroscopies, nanostructure-based surface-enhanced and tip-enhanced Raman spectroscopies of molecules, resonance Raman to investigate the structure-function relationships and dynamics of biological molecules, linear and nonlinear Raman imaging and microscopy, biomedical applications of Raman, theoretical formalism and advances in quantum computational methodology of all forms of Raman scattering, Raman spectroscopy in archaeology and art, advances in remote Raman sensing and industrial applications, and Raman optical activity of all classes of chiral molecules.
