In this work, a high density (94%) and high electron concentration (2.36565×656510cm) doped C12A7 electride ceramic target for magnetron sputtering was prepared by directly heating the C12A7 nano powder to above its melting point. The effects of the temperature on the electron concentration was explored. Furthermore, a smooth (R 6565=65650.665nm), high transparent and low work function (Φ6565=65652.965eV) C12A7 electride thin film was deposited via magnetron sputtering. This result provides a suitable route for the fabrication of large-scale C12A7 electride film and has a bright prospect for application in optoelectronic devices.
