CuO nanostructures doped with different concentration of Zn have been synthesized by a simple low-cost combustion method. The prepared samples have been tested by the various techniques such as X-ray diffraction (XRD), Transmission Electron Microscope (TEM), Optical absorption spectroscopy, Photoluminescence, and X-ray photoelectron spectroscopy (XPS). XRD confirmed the presence of the monoclinic phase of CuO along with an extra ZnO phase in the CuO:Zn. TEM results confirmed almost spherical - shaped nanoparticles as well as some irregular shaped NPs for pure CuO and Zn doped CuO with the average size from 24 to 54 nm. The change in morphology revealed a structural change in the CuO:Zn crystal due to different concentration of the Zn. The chemical study was done by XPS and the results were also correlated with XRD based results. The role of localized defects was compared and interpreted for the change in the luminescence spectral bands, micro-stains and oxidation states of the CuO:Zn for the different concentrations. CuO:Zn nanostructures demonstrated significant antifungal activities against two South African plant pathogens, Alternaria alternata CGJM3078 and Alternaria alternate CGJM3006, in comparison to pure CuO samples. The result showed that the pure and Zn doped CuO samples could be used as a good antifungal agent that could have an extensive applications in the agricultural and biotechnological industries.

通过简单的低成本燃烧方法已经合成了掺杂不同浓度的Zn的CuO纳米结构。所制备的样品已通过各种技术进行了测试，例如X射线衍射（XRD），透射电子显微镜（TEM），光学吸收光谱，光致发光和X射线光电子光谱（XPS）。XRD证实了CuO的单斜晶相以及CuO：Zn中额外的ZnO相的存在。TEM结果证实，纯CuO和Zn掺杂的CuO的纳米颗粒几乎为球形，并且具有一些不规则形状的NP，其平均粒径为24至54 nm。形态的变化揭示了由于Zn的不同浓度而导致的CuO：Zn晶体的结构变化。化学研究是通过XPS进行的，结果也与基于XRD的结果相关。比较了局部缺陷的作用，并解释了不同浓度下CuO：Zn的发光光谱带，微污点和氧化态的变化。CuO：Zn纳米结构显示出对两种南非植物病原体的显着抗真菌活性，与纯CuO样品相比，链格孢菌交替链CGJM3078和链格孢交替链CGJM3006。结果表明，纯锌掺杂的CuO样品可以作为良好的抗真菌剂，在农业和生物技术工业中具有广泛的应用。
