Light intensity in reflection mode of PAAO (3rd 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: 230 us. Scans to average: 10. Spectrum is recorded every 1 s 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 1 hour.本数据集记录了多晶铝阳极氧化过程中的光强数据。实验所用光源为SLS201L/M（ThorLabs），光谱仪为USB4000（OceanOptics），配套光谱采集软件为SpectraSuite（OceanOptics）。实验参数设置如下：积分时间230微秒，平均扫描次数为10次；阳极氧化过程中每1秒采集一次光谱数据。ref.txt文件包含阳极氧化过程启动前的参考光谱。本次阳极氧化实验在0.3 mol/L草酸电解液中，以40V恒压条件下持续1小时完成。
