摘要
A new kind Of MoO3/Au film was prepared by depositing Au nanoparticles on the surface Of MoO3 thin film through spin-on coating technique. After cathodic polarization, the MoO3/Au thin film was found to show enhanced visible-light coloration compared With MoO3 thin films. The formation of Schottky barrier at the MoO3/Au inter-face, and the visible-li.-ht coloration mechanism of the MoO3/Au film are elucidated by the energy band theory based on surface photovoltaic spectroscopy measurements.
