Abstract:
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).
