736CQDs3.1nmTEMThe statistical result displays that most of the CQDs' diameter are in the range of 2.1–4.5 nm with the average diameter of 3.1 nm (Fig. 1A, inset), demonstrating an excellent uniform particle size distribution.
1284CQDs3.1nmTEMAs can be observed, the CQDs are almost monodispersed spheres (Fig. 1A) with a uniform size distribution between 1.63 and 4.26 nm and an average diameter of 3.01 nm (Fig. 1B) based on measurements of 100 particles.
