For the development of electroluminescence devices made from anodic oxide films on aluminum, Eu ions were implanted into a barrier film, and red electroluminescence from Eu<sup>3+</sup> was observed during film reanodization.<br>Red electroluminescence from specimens without surface pretreatment occurred at about 100V and its intensity raised with increasing of voltage. It also continued for several minutes with a weak current density of 0.03mA·cm<sup>-2</sup> at a constant voltage of 350V.<br>Luminescence intensity was influenced by surface conditions, so electroluminescence from specimens without surface pretreatment was 7 times stronger than with electropolishing. Electroluminescence intensity was thus considered to be influenced by flaws in the film.
