Data on Particle Size Measurements and UV-visible Absorption Spectra of Gold Nanoparticles for "Synthesis of Precision Gold Nanoparticles Using Turkevich Method" Published in KONA Powder and Particle Journal, 2020, No.37, 224-232

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.
