Cost-effective and conductive metal nanoparticles play a key role of producing functional electronic devices using a printing technology. Currently, silver-based nanoparticles are used in printed technology due to their high conductivity and high oxidation resistance. However, silver is not cost-effective. Thus, Cu-based nanoparticles are considered to be a cost-effective alternative. However, Cu itself do not meet the requisition of high conductivity and oxidation stability, frequently. To solve this issue, Ag-coated Cu or CuO nanoparticles have been considered as the alternative for Ag. In this work, Ag/CuO nanoparticles were preapred by one-step spray pyrolysis with changing the mole ratio of Ag to Cu. The electrode was prepared by a thermal or photosintering treatment, and its electrical conductivity and oxidation stability was investigated. |
