摘要：

Photoluminescence spectra of thin-him aluminium oxide samples on aluminium show spectral lines at ca. 330 and 420 nm that are attributed to the F+ and F centers of aluminium oxide, respectively. Experimental results reveal that the F centers are responsible for the intrinsic cathodic luminescence of an oxide-covered aluminium electrode, too. The mechanism of the luminescence is based on charge transfer reactions at the oxide/electrolyte interface.
