A Facile Arc-Discharge Method to Deposit Metal Nanoparticles on Glass Substrate

This paper presents a simple low-cost approach to produce nanoparticles using arc-discharge method. Unlike existing deposition techniques, this is the first instance that nanoparticles are deposited on a charge neutral substrate by arc discharge method. In an atmospheric environment, copper (Cu) has been used as both anode and cathode in the process. The use of same material in both the electrode happens to be the first use case with arc discharge method. A simple airflow has been used to direct the evaporated nanomaterials towards the substrate. XRD, UV and FESEM were employed to confirm the presence of Cu nanoparticles and its properties. XRD pattern shows a crystal size of Cu nanoparticles as 7.4 nm.
