Light intensity in reflection mode of PAAO (1st sample 2nd anodization)

Light intensity data recorded during the anodization of aluminum polycrystal. Light source: SLS201L/M (ThorLabs). Spectrometer: USB4000 (OceanOptics). Spectra acquisition software: SpectraSuite (OceanOptics). Integration time: 340 us. Scans to average: 5. Spectrum is recorded every 50 ms during anodization. ref.txt includes reference spectra just before the start of anodization process. Anodization was performed in 0.3 mol/L oxalic acid at 40 V for 6 min. The research was carried out under postdoctoral project "Patterned hybrid multilayer films for optical sensors", No. 1.1.1.2/VIAA/4/20/615.
