摘要
This paper reports the optical and electrical properties of electrochemically deposited polyaniline （PANI）/cerium oxide（CeO;） hybrid nano-composite film onto indium-tin-oxide（ITO） glass substrate.UV-visible spectroscopy andⅠ-Ⅴcharacteristic were performed to study the optical and electrical parameters of the electrochemically deposited film.The film exhibited a strong absorption below 400 nm（3.10 eV） with a well defined absorbance peak at around 285 nm（4.35 eV）.The estimated band gap of the CeO;sample was 3.44 eV,higher than bulk CeO;powder（E;= 3.19 eV） due to the quantum confinement effect.Optical and electrochemical characteristics indicated that the electrical properties of PANI/CeO;hybrid nanocomposite film arc dominated by PANI doping.
