摘要

在本研究中，采用溶胶-凝胶自燃烧法，在800℃退火后，成功合成了一系列不同钴浓度（15、25、35和45%）的纯钴和掺杂钴的氧化锌纳米颗粒样品。用x射线衍射仪对晶体结构进行了表征，发现所有合成样品均具有六方纤锌矿结构。报道了晶格常数（a和c）、晶粒尺寸(D)、晶胞体积(V)和微应变（ε）。采用Williamson-Hall图和尺寸-应变图来了解合成样品的结构和力学属性。

Modifying Zinc Oxide Nanoparticles: The Role of Cobalt Doping on Structural and Mechanical Behavior

In the present study, a series of pure and cobalt-doped zinc oxide nanoparticle samples with different concentrations (15, 25, 35, and 45%) of cobalt were successfully synthesized using sol–gel auto-combustion method followed by annealing at 800°C. The crystal structure was characterized using an X-ray diffractometer, revealing that all synthesized samples had hexagonal wurtzite structure. The lattice constants (a and c), crystallite sizes (D), unit cell volume (V), and microstrain (ε) were reported. The Williamson–Hall plot and size–strain plot were also employed to understand the structural and mechanical attributes of the synthesized samples.

期刊介绍： International Journal of Self-Propagating High-Temperature Synthesis is an international journal covering a wide range of topics concerned with self-propagating high-temperature synthesis (SHS), the process for the production of advanced materials based on solid-state combustion utilizing internally generated chemical energy. Subjects range from the fundamentals of SHS processes, chemistry and technology of SHS products and advanced materials to problems concerned with related fields, such as the kinetics and thermodynamics of high-temperature chemical reactions, combustion theory, macroscopic kinetics of nonisothermic processes, etc. The journal is intended to provide a wide-ranging exchange of research results and a better understanding of developmental and innovative trends in SHS science and applications.
