Fig. 1From: Reversible Electrochemical Control over Photoexcited Luminescence of Core/Shell CdSe/ZnS Quantum Dot FilmCyclic voltammetry of CdSe/ZnS QD film (solid) and ITO (dashed) at 100 mV/s. The peak at − 1.7 V is attributed to the charging of 1Se state, and the peak at − 1.2 V is attributed to the charging of surface trap states. The arrows indicate the scan direction. The Ag quasi-reference is offset by 65 mV versus standard hydrogen electrode (SHE)Back to article page
