Abstract

Strontium zirconium di-orthophosphate was synthesized by solid state method. The phase purity and its crystal structure was studied through X-ray diffraction pattern. It was observed that powder has triclinic structure. The functional group was identified from the Fourier transform infrared spectrum. The energy band gap was determined from Wood and Tauc plot, derived from Ultraviolet-visible spectrum, confirms that the matrix is an insulator. Capacitance studies indicate possible applications of these phosphates in super-capacitors. Thermoluminescence glow curves were recorded with constant heating rate at 5 °C/s after exposing into gamma radiations of different fluences. The trapping parameters such as kinetic orders, frequency factor and activation energy factors were calculated. These results demonstrate the possible application of Strontium zirconium di-orthophosphate as a dosimeteric material to measure gamma ray exposure.

摘要

采用固相法合成了二正磷酸锶锶。通过X射线衍射图研究了相纯度及其晶体结构。观察到粉末具有三斜结构。该官能团是从傅立叶变换红外光谱中鉴定出来的。根据伍德和陶克图（由紫外线-可见光谱得出）确定能带隙，证实该基质为绝缘体。电容研究表明这些磷酸盐在超级电容器中的可能应用。暴露于不同通量的伽马射线后，以恒定的加热速率以5°C / s记录热致发光辉光曲线。计算了动力学参数，频率因子和活化能因子等捕获参数。
