摘要：
The presented results of our galvatioluminescence measurements of porous oxide films formed by anodization of aluminum in phosphoric acid show strong influence of the surface pretreatment of samples and concentration of impurities on galvanoluminescence intensity. We have also presented the influence of anodic conditions (current density, temperature of electrolyte and electrolyte concentration) on GL intensity. For the first time, spectral measurements of galvanoluminescence for early stage of film growth (barrier type of films) as well as for thick porous film are performed. We have obtained identical spectra with two spectral peaks at about 425 and 595 nm. (C) 2004 Elsevier B.V. All rights reserved.
