Luminescence, breakdown and colouring of anodic oxide films on aluminium
TL;DR: In this article, the breakdown and self-colouring phenomena of anodic oxide films on aluminium, which have been found to be closely related with each other, were reviewed according to newly proposed classifications.

Nature of luminescence during galvanostatic anodizing of high purity aluminium
TL;DR: Galvanoluminescence of high purity aluminium was found to have two fundamental origins: one was the luminescence associated with scintillation or with some concommitant side reactions, taking place at the flaws; the other was the luminosity associated with anions included in the films during anodization as mentioned in this paper.

Localized nature of the luminescence during galvanostatic anodizing of high purity aluminium in inorganic electrolytes
K. Shimizu,S. Tajima +1 more
TL;DR: In this paper, the intensity of the luminescence was found to be closely correlated with the concentration of "flaws" in the growing oxide film, which is a local phenomenon which takes place at "flaw" in growing oxide films.

Theory of electroluminescence of Al/anodic alumina/electrolyte system
K. Shimizu,S. Tajima +1 more
TL;DR: In this article, a relationship between the intensity of luminescence, L, and the film thickness, d, was obtained theoretically for the electroluminescence of the Al/anodic alumina/electrolyte system.

Electron-microscopic and optical studies on the electrocrystallization of alpha-alumina (corundum) films on aluminium☆
TL;DR: In this article, electron micrographs have been taken on the top surfaces, crosssections and bottom of the oxide films, and on the surface of the substrate metal, under various conditions of electrolysis; also, comparison was made with the conventional sulphuric acid anodizing films.
