Sažetak
The processes of formation and galvanoluminescence (gl) of anodic oxide film of ultra–high purity Al in ammonium tartrate as electrolyte have been investigated. Many important differences have been found in comparison with the case of inorganic electrolytes.
First, under the same conditions gl intensity in ammonium tartrate is 2–5 times greater than in boric acid–borax solution.
Second, gl intensity is approximately a linear function of the film thickness d, including the case of annealed samples to which in inorganic electrolytes corresponds an exponential growth of Nλ vs d.
Third, gl spectrum corrected for interference effects has, in the range 400–750 nm, only one broad maximum instead of at least five maxima found in inorganic electrolyte.
These differences should be attributed to the different nature of luminescence in the two cases investigated.
