摘要：

Results are reported from a study of the optical properties of porous alumina films obtained by anodizing in a water solution of sulfuric acid and modified by thermal annealing in air at T >= 850 degrees C. A comparative analysis of the data shows that the near-UV and visible photoluminescence of alumina anodized in a sulfuric acid solution is caused primarily by oxygen divacancies (F-2, F-2(+), and F-2(2+) centers), while sulfate ions have little effect on the luminescence properties of anodic alumina in this spectral range.
