Figure 5.

Transient potentiometric data for photodoping d = 3.8 nm Cd²⁺-enriched (red) and Se^2--enriched (blue) CdSe NCs with Na[Et₃BH] as the hole quencher in a THF solution with 0.1 M TBAPF₆ as the supporting electrolyte. For each sample, the NCs were photodoped using a 405 nm diode (50 mW) between t = 1 and 5 min. At t = 5 min, photoexcitation was stopped but E_F was monitored further. Inset: A/A₀ collected in concert with E_F.
