The Excel spreadsheet contains the UV-visible spectrum analysis of Fig. 1 and the raw particle size measurements used to plot Fig. 2 of the present manuscript. The UV-visible spectra were analyzed using the Peak Analyzer function in OriginLab. The particle size was measured using dynamic light scattering (DLS), which was then analyzed using Microsoft Excel. The intensity distribution was directly obtained from the DLS measurement. The volume and number distributions were calculated from the intensity distribution by Malvern Zetasizer internally.
