Light intensity in reflection mode of PAAO (2nd sample 1st 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: 250 us. Scans to average: 10. Spectrum is recorded every 1 s during anodization. ref.txt includes reference spectra before the start of anodization process. Anodization was performed in 0.3 mol/L oxalic acid at 40 V for 1 hour. The research was carried out under postdoctoral project "Patterned hybrid multilayer films for optical sensors", No. 1.1.1.2/VIAA/4/20/615.
