A cost-effective phytogenic fabrication of zinc oxide (ZnO) and copper-doped zinc oxide (Cu-doped ZnO) using aqueous leaf extract of Ziziphus mauritiana Lam. was successfully demonstrated. The structural, morphological and optical studies have been carried out using various techniques. XPS, XRD analysis and FT-IR spectroscopic studies confirmed the successful synthesis, crystalline nature and purity of synthesized ZnO and Cu-doped ZnO. UV-visible diffuse reflectance spectra showed reduction of band gap energies from 3.11 to 2.54 eV as Cu doping increases from 0% to 5%. SEM images revealed the synthesized ZnO and Cu-doped ZnO are irregular and spherical shaped, respectively. Antibacterial property of the synthesized materials were evaluated against Gram positive Staphylococcus aureus and Gram negative Escherichia coli using different concentrations. This investigation revealed that the synthesized materials were able to inhibit the activity of Staphylococcus aureus better than Escherichia coli under both dark and visible light conditions with the highest inhibition of 9.33 ± 0.58 mm under light irradiation. The synthesized materials were also found to effectively scavenge 2,2-diphenyl-1-picrylhydrazyl radicals in the dark and an enhancement of the scavenging activity was observed under visible light irradiation.

使用Zipziphus mauritiana Lam的叶子提取物，经济高效地生产氧化锌（ZnO）和铜掺杂的氧化锌（Cu掺杂的ZnO）。被成功演示。已经使用各种技术进行了结构，形态和光学研究。XPS，XRD分析和FT-IR光谱研究证实了合成的ZnO和掺杂Cu的ZnO的成功合成，晶体性质和纯度。紫外可见漫反射光谱显示， 随着铜掺杂从0％增加到5％，带隙能量从3.11降低到2.54 eV。SEM图像显示合成的ZnO和Cu掺杂的ZnO分别为不规则形状和球形。评价了合成材料对革兰氏阳性金黄色葡萄球菌的抗菌性能和革兰氏阴性大肠杆菌使用不同的浓度。这项研究表明，合成材料在黑暗和可见光条件下均能比大肠杆菌更好地抑制金黄色葡萄球菌的活性，在光照射下的抑制作用最高，为9.33±0.58 mm。还发现合成的材料在黑暗中有效清除了2，2-二苯基-1-吡啶并肼基，并且在可见光照射下观察到了清除活性的增强。
