Light intensity in reflection mode of PAAO (AJ-4-04-20 sample, 2nd anodization)

Light intensity data recorded during the anodization of aluminum monocrystal.

Light source: SLS201L/M (ThorLabs).

Spectrometer: USB4000 (OceanOptics).

Spectra acquisition software: SpectraSuite (OceanOptics). Integration time: 360 µs. Scans to average: 10. Spectrum is recorded every 500 ms during anodization. ref.txt includes reference spectra just before the start of anodization process. All measurements data is also included in a single "AJ-1-04-20.zip" file.

Anodization was performed in 0.3 mol/L oxalic acid at 40 V for 4 min 30 s.
