采用大气热化学气相沉积法合成了Ni纳米颗粒，并利用Bragg相干衍射成像研究了其晶格畸变和缺陷。由于应变会改变铁磁材料的磁性，因此对其晶格畸变和结构缺陷的研究具有重要意义。通过Bragg相干衍射成像，我们发现镍纳米立方体的中间有一个无变形区。此外，基于Bragg衍射图像和图形，在其他Ni纳米颗粒中发现了位错和孪晶畴缺陷。纳米颗粒的成像有助于更好地理解其生长机制，改进纳米颗粒的设计和合成。
We synthesized Ni nanoparticles with an atmospheric-thermal chemical vapor deposition method and investigated their lattice distortions and defects using Bragg coherent diffractive imaging. Because the strain can alter the magnetic properties of ferromagnetic materials, it is important to study the lattice distortion and structural imperfection. As a result of the Bragg coherent diffractive imaging, we found that the Ni nanocubes have a deformation-free zone in the middle. In addition, the defects such as dislocation and twin domain defects were detected in other Ni nanoparticles based on the Bragg diffraction images and patterns. The imaging of nanoparticles can contribute to a better understanding of their growth mechanisms and improve the design and synthesis of nanoparticles.
