Abstract
An electronic method, based on the differentiation of the potential curve during anodization at a constant current, is presented for evaluating the number of breakdown events in the scintillation of anodic oxides. This simple method facilitates the study of the breakdown phenomenon in anodic oxides as a function of the anodization current density, nature and resistivity of the electrolyte, etc. The results are briefly discussed according to a proposed model of the scintillation mechanism.
