Firstly, new copper precursor was prepared from the mixture of Cu(CH3COO)2∙H2O and salicylic acid (1:1 weight ratio) ground for 5 min, and secondly, copper oxide nanoparticles were prepared by calcination of copper precursor at 500 ºC and 600 ºC for 1.5 h. The products were characterized by Fourier Transform infrared, UV–Vis and photoluminescent spectroscopy, X-ray powder diffraction, and transmission electron microscopy. The FT-IR, UV–Vis, PL, and XRD analysis confirmed the formation of CuO nanoparticles of high purity with a monoclinic structure. TEM images showed that the nanoparticles in both samples had almost similar shape with high agglomeration. In addition, antibacterial activity against two gram-positive and two gram-negative stains were studied.
