Abstract

Copper oxide (CuO) nanoparticles have been successfully synthesized by microwave assisted - precipitation
technique. In terms of advanced nanostructure synthesis, microwave method in which copper hydroxide
nanostructures are produced in the precursor solution and sequentially transformed by microwave into CuO
may be considered as a promising method. To explore, the blend of two methods adopted was very simple and
reliable. This gives a large scale production of CuO nanoparticles easily with a brilliant band gap of 1.55 eV. This
method produces not only large quantities of nano yield in a short reaction time but also high-quality materials
with advanced properties. The structural, morphological, and optical properties of CuO nanoparticles have been
studied and reported.
