No TL;DR found
Abstract
Cuprous oxide (Cu2O) nanoparticles are synthesized by aqueous precipitation method for the production of low-cost conductive ink, which is suitable for a printed, electronic application. The major drawback of copper ink, such as rapid oxidation overcomes by the formation of Cu2O ink. Structural characterizations reveal that spherical, nano-sized, polycrystalline cubic structure of Cu2O nanoparticles synthesized in the present work. The studies on transmission electron microscopies show that the size of these nanoparticles is approximately 7.5 ± 1.8 nm. The Cu2O nanoparticles show an absorption band at 650 nm with a bandgap of 2 eV. Results of sheet resistance and contact angle of Cu2O nanoparticles make it suitable for the development of low-cost conductive writing ink for a printed, electronic application.
