Nowadays, nanotechnology offers opportunities to create new features and functions of emerging materials. Correlation studies of nanostructured materials' development processes with morphology, structure, and properties represent one of the most important topics today due to potential applications in all fields: chemistry, mechanics, electronics, optics, medicine, food, or defense. Our research was motivated by the fact that in the nanometric domain, the crystalline structure and morphology are determined by the elaboration mechanism. The objective of this paper is to provide an introduction to the fundamentals of nanotechnology and nanopowder production using the sun's energy. Solar energy, as part of renewable energy sources, is one of the sources that remain to be exploited in the future. The basic principle involved in the production of nanopowders consists of the use of a solar energy reactor concentrated on sintered targets made of commercial micropowders. As part of our study, for the first time, we report the solar ablation synthesis and characterization of Ni-doped ZnO performed in the CNRS-PROMES laboratory, UPR 8521, a member of the CNRS (French National Centre for Scientific Research). Also, we study the effect of the elaboration method on structural and morphological characteristics of pure and doped ZnO nanoparticles determined by XRD, SEM, and UV-Vis.
如今，纳米技术为创造新兴材料的新特性和功能提供了机遇。纳米结构材料的发展过程与形态、结构和性能之间的相关性研究是当今最重要的课题之一，因为其在化学、力学、电子学、光学、医学、食品或国防等所有领域都有潜在应用。我们的研究动机源于这样一个事实：在纳米领域，晶体结构和形态由制备机制决定。本文的目的是介绍纳米技术的基本原理以及利用太阳能生产纳米粉末的方法。太阳能作为可再生能源的一部分，是未来有待开发的能源之一。生产纳米粉末所涉及的基本原理是使用太阳能反应器，该反应器聚焦于由商业微粉制成的烧结靶材。作为我们研究的一部分，我们首次报告了在法国国家科学研究中心（CNRS）下属的UPR 8521实验室——CNRS - PROMES实验室中进行的镍掺杂氧化锌的太阳能烧蚀合成及表征。此外，我们还研究了制备方法对通过X射线衍射（XRD）、扫描电子显微镜（SEM）和紫外可见光谱（UV - Vis）测定的纯氧化锌和掺杂氧化锌纳米颗粒的结构和形态特征的影响。
