论文摘要
可以用作高压传感器的功能材料受到限制，从而使人们受到追捧。据报道，静水压力极大地影响了ZRSIO4的拉曼偏移。因此，已建议硅酸锆为拉曼光谱压力传感器。但是，基于拉曼的传感器技术的大规模应用构成了广泛的挑战。我们证明ZRSIO4还表现出压力依赖性红外（IR）光谱。此外，ZRSIO4的IR峰对剪切应力和非静压压力敏感，使该材料成为通过IR光谱确定各种机械应力的独特传感器。
Functional materials that can serve as high-pressure transducers are limited, making such sensor material sought after. It has been reported that hydrostatic pressures highly influence Raman shifts of ZrSiO4. Therefore, zirconium silicate has been suggested as a Raman spectroscopic pressure sensor. However, mass applications of a Raman-based sensor technology poses a wide range of challenges. We demonstrate that ZrSiO4 also exhibits pressure-dependent infrared (IR) spectra. Furthermore, the IR peaks of ZrSiO4 are sensitive to shear stresses and non-hydrostatic pressures, making this material a unique sensor for determining a variety of mechanical stresses through IR spectroscopy.
