In recent years, there have been few thousands of non-linear optical (NLO) materials proposed for a wide array of technological applications. But unfortunately, most of the materials do not fit into the actual standard required for the specific purposes in terms of their efficiency, environmental resistance, cost effectiveness, availability, stability and durability. Hence, searching for the most suitable material for every specific technological application has become the necessity of being a continuous process until it is found. For the present experiment, we have chosen benzophenone crystal for the shock wave recovery experiment. Raman and powder X-ray diffraction (XRD) techniques have been utilized to evaluate the molecular and structural performances of the title material against the impact of shock waves and the obtained crystallographic structural properties are compared with potassium dihydrogen phosphate (KPD) crystal. The obtained Raman and XRD results demonstrate that the title material has high shock resistant property even though it is a mechanically soft material as well as it has very low melting point (48 °C).

冲击波加载条件下二苯甲酮晶体稳定性的光谱评估。
近年来,已经提出了数千种用于多种技术应用的非线性光学(NLO)材料。但是不幸的是,大多数材料在效率,耐环境性,成本效益,可用性,稳定性和耐用性方面均不符合特定目的所需的实际标准。因此,为每种特定技术应用寻找最合适的材料已成为必须持续进行直到发现的连续过程的必要性。对于本实验,我们选择了二苯甲酮晶体作为冲击波恢复实验。拉曼和粉末X射线衍射(XRD)技术已用于评估标题材料在冲击波作用下的分子和结构性能,并将获得的晶体结构特性与磷酸二氢钾(KPD)晶体进行比较。所获得的拉曼和XRD结果表明,标题材料即使是机械上柔软的材料,也具有很高的耐冲击性,并且熔点很低(48℃)。
