Abstract

Silver oxide nanoparticles (AgO NPs) were synthesized by implementing chemical reduction process and two different samples of AgO NPs were loaded with 100 as well as 200 pulses of successive shock waves of Mach number 2.2 so as to investigate the aftermath effect. Various characteristic analytical techniques were carried out for the samples utilizing Powder X-ray diffractometer (PXRD), Ultra-Violet diffuse reflectance spectroscope (UV-DRS), Field emission scanning electron microscope (FE-SEM) and Vibrating sample magnetometer (VSM) to find stabilities of crystallographic, spectroscopic, morphological and magnetic behaviors and also to analyze the changes occurring on the properties of the test material due to the impulsion of shock waves. From the obtained XRD patterns, the mean value of grain sizes of unshocked, 100 and 200 shocked AgO NPs is found to be 20, 20.6 and 26 nm, respectively. FE-SEM images reveal that the mean values of particle sizes increase as the counting of shock pulses are increased. The particles sizes are computed to be 72 nm, 112 nm, and 162 nm for the unshocked, 100 and 200 shocked AgO NPs, respectively. Whereas, the values of magnetization of AgO NPs have reduced with regard to the number of shock waves in such a way that the value of 2.183 emu/g for the unshocked AgO NPs is found to have reduced to 1.801 and 1.416 emu/g for 100 and 200 shocks, receptively. The band gap energy of the unshocked and shocked AgO NPs is observed to have the same value of 2.1 eV. From the experiential results, it is very well established that the title material’s properties such as crystalline and molecular structure, band gap energy are stable; whereas, the magnetic properties and surface morphology undergo subtle changes at shocked conditions.

冲击条件下纳米氧化银（AgO）的结构，光学和磁性

摘要

通过化学还原过程合成了氧化银纳米粒子（AgO NPs），并在两个不同的AgO NPs样品中加载了100脉冲和200脉冲的马赫数为2.2的连续冲击波，以研究后果。利用粉末X射线衍射仪（PXRD），紫外漫反射光谱仪（UV-DRS），场发射扫描电子显微镜（FE-SEM）和振动样品磁力计（VSM）对样品进行了各种特性分析技术找出晶体学，光谱学，形态学和磁学行为的稳定性，并分析由于冲击波的冲击而使测试材料的性能发生变化。根据获得的XRD图谱，未冲击的晶粒尺寸平均值 发现100和200个受电击的AgO NP分别为20、20.6和26 nm。FE-SEM图像显示，随着冲击脉冲计数的增加，粒径的平均值也随之增加。对于未震荡的100和200震荡的AgO NP，计算出的粒径分别为72 nm，112 nm和162 nm。鉴于冲击波的数量，AgO NPs的磁化强度有所降低，以至于未震荡的AgO NPs的2.183 emu / g的含量已降低至1.801和1.416 emu / g。并接受200次电击 观察到未震动和震动的AgO NP的带隙能量具有相同的2.1 eV值。根据实验结果，可以很好地确定标题材料的性质，例如晶体和分子结构，带隙能量是稳定的。而，
