The energy gap, ËGydF4y2Ba GGydF4y2Ba of NPs, was found to be 2.19 eV. FTIR spectra confirmed the presence of polyphenols, tannins, and glycosides in the leaf extract of Hagenia abyssinicaGydF4y2Ba。该spectral band at 740 cm^-1GydF4y2Ba为Cu和提取物的生物分子之间的相互作用的特征。XRD分析表明，克 - 铜纳米颗粒似乎是在本质上更加结晶的。SEM和TEM显微照片显示球形的，六边形，三角形，圆柱形和不规则形状的Cu粒子的混合。该average particle size of NPs was found to be 34.76 nm by ImageJ analysis. EDX analysis confirmed the presence of copper in the g-Cu NPs. In addition, the SAED pattern of g-Cu NPs presented concentric circular patterns for 4 major planes of crystalline copper and its oxides. The experimental and calculated dGydF4y2Ba -spacing values of one of the crystal planes (111) were found to be 0.2432 nm and 0.2444 nm, respectively. The dGydF4y2Ba -spacing values of 0.2444 nm and 0.2040 nm correspond to d_111GydF4y2Ba铜GydF4y2Ba_2GydF4y2BaO和dGydF4y2Ba_111GydF4y2Ba铜晶格条纹，分别。抗菌试验进行了GydF4y2Ba 大肠杆菌GydF4y2Ba，GydF4y2Ba 铜绿假单胞菌GydF4y2Ba，GydF4y2Ba 金黄色葡萄球菌GydF4y2Ba和GydF4y2Ba 枯草芽孢杆菌GydF4y2Bashowed good zone of inhibitions 12.7, 12.7, 14.7, and 14.2 mm, respectively, proving potentiality of g-Cu NPs as a remedy for infectious diseases caused by tested pathogens.
