(A) Cyclic voltammograms and (B) magnification of the CD cyclic voltammogram. (C) ECL signals of a CSPE in a solution of: electrolyte (0.2 M PB pH 8) (black line), 8 mg/mL CDs (red line), 7 mM [Ru(bpy)₃]²⁺ (orange line) and 7 mM [Ru(bpy)₃]²⁺ with 8 mg/mL CDs (blue line) in 0.2 M PB pH 8. (D) Proposed mechanism for the [Ru(bpy)₃]³⁺/CD system. (E) 3D ECL spectrum of [Ru(bpy)₃]²⁺/CD system. These measurements were performed using 0.2 M PB pH 8 as electrolyte and applying a cyclic potential scan from 0.60 V to 1.30 V with a scan rate of 10 mV/s.
