Researchers around the world are keen to understand the physical phenomena underlying these nanomaterials. Metal oxide nanoparticles, in particular, have garnered attention in the electronics industry due to their semiconductor behaviour, high dielectric constants, and tunable band gaps. Among these, copper oxide (CuO) nanoparticles stand out for their unique properties, making them particularly appealing for optoelectronics and solar cell applications. In this current research, our aim was to synthesize copper oxide nanoparticles and manganese (Mn)-substituted copper oxide nanoparticles using an environmentally friendly approach. We utilized aloe vera to produce CuO nanoparticles, offering a green alternative to traditional toxic chemical synthesis methods without inducing any phase changes. The methodology involved the eco-friendly synthesis (Aloe vera act as fuel) of pure and Mn-doped CuO nanoparticles, followed by a comprehensive investigation of their structural, optical, and electrical properties. The findings revealed that the reduced optical bandgap of Mn-doped CuO nanoparticles is 1.09 eV. Additionally, the dielectric constant of the doped CuO nanoparticles showed an enhanced value (ɛr = 1485) with minimal loss less than one. In conclusion, the Mn-doped CuO nanoparticles prepared through this novel eco-friendly method exhibit beneficial electrical and optical properties, making them highly suitable for optoelectronic applications.
