Impact of shock waves on non-linear optical materials bring about a lot of unknown behaviors of materials and such kinds of shock wave recovery experiments are highly required for the better understanding of material-property relationship. In the present context, we have performed experiments on the impact of structural properties of ammonium dihydrogen phosphate (ADP) samples under shock wave loaded conditions and the results of the test samples have been evaluated by X-ray diffraction (XRD), Raman spectroscopy, diffused reflectance spectroscopy (DRS) and field emission scanning electron microscopic (FESEM) technique. Interestingly, prismatic face of ADP shows loss of degree of crystallinity whereas pyramidal face shows enhancement of crystalline nature with respect to number of shock pulses due to shock wave induced dynamic re-crystallization. Hence, the present problem is worthy enough to unearth and understand the anisotropic nature of the ADP crystal and their structural modifications at shock wave loaded conditions.

X射线和拉曼散射研究震荡磷酸二氢铵的相稳定性

冲击波对非线性光学材料的影响带来了许多未知的材料行为，为了更好地了解材料与特性之间的关系，迫切需要进行此类冲击波恢复实验。在目前的环境下，我们已经进行了关于在冲击波加载条件下磷酸二氢铵（ADP）样品的结构性能影响的实验，并且通过X射线衍射（XRD），拉曼光谱法对测试样品的结果进行了评估，扩散反射光谱（DRS）和场发射扫描电子显微镜（FESEM）技术。有趣的是，由于冲击波引起的动态重结晶，ADP的棱柱面显示出结晶度的损失，而锥体面显示出相对于冲击脉冲数而言的结晶性增强。
