8347 1342 AgNPs@GQDs 14-24 nm TEM In comparison, AgNPs without the assembly of GQDs show the morphology with a little aggregation (Fig. S1 in Supporting information), which are smaller than that of AgNPs@GQDs (14−24 nm). Upon treating with H2O2, the characteristic nanoparticles of AgNPs@GQDs disappear, and the monodisperse nanodots with the average diameter of 6.7 nm are observed in TEM image 25.3479
