Characterization and Analytical Separation of Fluorescent Carbon Nanodots

Figure 11

Characterization of the surface chemistry of three kinds of C-dots derived from different materials: (a) proton binding curves of C-dots samples. (b) DTG curves of C-dots samples in helium. ((c)–(e)) Selected MS patterns of C-dots samples (multiplication factor: MW-16 ([O]) × 7; MW-28 (CO) × 1; MW-44 (CO₂) × 5; MW-48 (SO) × 500; MW-64 (SO₂) × 500) [93].
