In this work, we successfully synthesised highly transparent and conducting CuI thin films at room temperature via a rapid chemical reaction between the Cu3N precursor and aqueous iodine solution. The effect of the precursor (Cu or Cu3N) on the structural, electrical, and optical properties of the CuI thin films was investigated. The X-ray diffraction results revealed that the prepared films were polycrystalline, preferentially oriented along the (111) planes of the zinc blende structure. In addition, we found that the nitrogen content of the precursor significantly affected the optical and electrical properties of the CuI films. The CuI film obtained by dipping Cu3N film into aqueous iodine solution for 1 min exhibited a conductivity of 29.36 Scm−1 and transmittance of 75% in the visible region. We expect that these findings would assist researchers to rapidly synthesise CuI thin films for transparent electronic devices.
