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.

Cu2O纳米粒子的合成与表征

摘要 通过水性沉淀法合成氧化亚铜 (Cu2O) 纳米颗粒，用于生产低成本的导电油墨，适用于印刷电子应用。铜墨水的主要缺点，例如快速氧化，通过形成 Cu2O 墨水来克服。结构表征表明，在本工作中合成了球形、纳米级、多晶立方结构的 Cu2O 纳米颗粒。对透射电子显微镜的研究表明，这些纳米颗粒的尺寸约为 7.5 ± 1.8 nm。Cu2O 纳米粒子在 650 nm 处显示吸收带，带隙为 2 eV。Cu2O 纳米颗粒的薄层电阻和接触角的结果使其适用于开发用于印刷电子应用的低成本导电书写墨水。
