Black phosphorus quantum dots (BPQDs) have shown promising applications in biosensors and energy storage devices. However, the electrochemiluminescence (ECL) properties of pristine BPQDs an organic system rarely been reported. In this paper, N,N′-dimethylformamide passivated with a small size 2.3 nm were obtained by ultrasonication-assisted liquid exfoliation process, their ECL studied. A reversible reduction peak was recorded differential pulse voltammetry, while no apparent oxidation observed. signal not seen annihilation route. Persulfate proved to be effective coreactant yellow emission observed which greatly red-shifted comparison that photoluminescence. is believed generated from both surface states electron promotion over band gap.
