Synthesis and Characterization of Undoped and Mn-Doped Copper Oxide Nanoparticles

Copper oxide (CuO) is a p-type metal-oxide semiconductor with a bandgap of 1.2 eV and a minimal bandgap. Solar cells, superconductors, and sensors are among the applications for which it is used. To dope transition metals, researchers use a low-cost soft chemical process (Mn). The aim of this research is to identify CuO nanopowders using a low-cost soft chemical method to dope transition metals (Mn). The nanopowders' structural, morphological, functional, and optical properties are investigated. X-ray diffraction (XRD) analysis findings point to the synthesis of high purity single monoclinic phase CuO nanoparticles. The crystallite size (30 nm) and lattice parameters of Mn-doped CuO samples are reduced. These results suggest that Mn-doped CuO nanoparticles may be a promising candidate for optoelectronic devices and photocatalytic organic compound degradation.
