- Abstract
In this present work, Ni doped CuO nanoparticles were successfully prepared by chemical precipitation method. The structural and chemical compositions of the products were characterized by X-ray diffraction, Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy. The obtained products were identified to be of monoclinic structure and these results demonstrate that the Ni ions were substituted into the CuO lattice. The optical properties of the products were studied by diffuse reflectance spectroscopy and room temperature photoluminescence measurements. The morphological analyses were obtained by using field emission scanning electron microscopy and transmission electron microscopy. The magnetic properties were investigated at room temperature using the vibrating sample magnetometer and the hysteresis loops confirmed the ferromagnetic behaviour of CuO on doping due to smaller size effect. Further, as-formed doped and undoped CuO nanoparticles exhibit significant antibacterial activity against pathogenic bacterial strains namely Gram −ve ( Pseudomonas aeruginosa, and Escherichia coli), Gram +ve bacteria ( Bacillus subtilis, Staphylococcus aureus).
