This paper presents the synthesis of Barium Oxide Nanoparticles (BaO-NPs) on a large-scale by a simple and cost-effective co-precipitation method. The as-synthesized BaO-NPs were characterized in aspects of their structural, morphological, compositional, and optical properties. X-ray diffraction was done to assess the crystalline property of the nanomaterial and the crystallite size of the BaO-NPs was found to be 15–16 nm. Scanning electron microscopy was used to study the morphology of as-synthesized nanoparticles which confirmed that the prepared materials are flower-shaped nanoparticles. The compositional characteristics of nanoparticles were given by Fourier transform infrared spectroscopy which confirmed that the as-synthesized nanoparticles are pure BaO. A useful optical properties of nanoparticles were also reported via the room temperature UV–Vis and photoluminescence spectroscopy and calculated bandgap of the nanoparticles was found 4.65 eV.
