• We report a method to purify graphene quantum dots size simply by adding ammonium sulfate. The addition of a salt to a heterogeneous GQD suspension results into the sorting of GQD sub-populations with diameters corresponding to 2.7 ± 1.6, 5.1 ± 1.5, 13.3 ± 1.9, and 18.7 ± 4.4 nm. These GQDs also exhibit different optical properties.
