Abstract

Cr-doped ZnO ( $x = 0.02$ –0.08) nanoparticles are synthesized using the microwave solvothermal irradiation technique. The final product is calcinated at 450^∘C and the nanostructure of the material is investigated using various techniques. In structural studies, XRD analysis shows that the hexagonal wurtzite structure of ZnO is present in the standard JCPDS card. FESEM spectrum reveals the hexagonal shape of the synthesized samples and EDS provides information on the qualitative composition of the nanoparticles. Optical absorbance images show exciton peaks in the UV region, which can be attributed to Cr incorporation into the ZnO lattice, and the optical energy bandgap values are calculated using the tauc plot method. Photoluminescence (PL) emission spectra are measured using PL spectroscopy. Interestingly, vibrating sample magnetometry (VSM) reveals enhancements in the magnetic properties in M–H loops and it is widely used for biological applications like antibacterial activity.

通过简便的溶热路线合成掺杂铬的氧化锌纳米粒子并确定其特性

利用微波溶热辐照技术合成了掺杂铬的氧化锌（x=0.02-0.08）纳米粒子。最终产品在 450∘C 煅烧，并使用各种技术研究了材料的纳米结构。在结构研究中，X 射线衍射分析表明，氧化锌的六方晶格结构存在于标准的 JCPDS 卡中。FESEM 光谱显示了合成样品的六边形，而 EDS 则提供了有关纳米颗粒定性组成的信息。光学吸光度图像显示了紫外区的激子峰，这可能是由于铬掺入到氧化锌晶格中，并使用陶氏图法计算了光能带隙值。使用 PL 光谱法测量了光致发光（PL）发射光谱。有趣的是，振动样品磁力计（VSM）揭示了 M-H 循环中磁性能的增强，它被广泛应用于抗菌等生物领域。

期刊介绍： Launched in 1987, the International Journal of Modern Physics B covers the most important aspects and the latest developments in Condensed Matter Physics, Statistical Physics, as well as Atomic, Molecular and Optical Physics. A strong emphasis is placed on topics of current interest, such as cold atoms and molecules, new topological materials and phases, and novel low dimensional materials. One unique feature of this journal is its review section which contains articles with permanent research value besides the state-of-the-art research work in the relevant subject areas.
