(a) I-V curve of the ITO/CEA:GQD/Al device when a negative voltage from 0 to −3 V is applied in the 2nd sweep. The inset shows a fitting of the I-V data with a ln (I) versus V0.5 curve for the device under a negative voltage from 0 to −1.2 V (region I in (a)). (b) Fitting of the I-V data with a ln (I) versus ln (V) curve under a negative voltage from −2.3 to −3 V (region II in (a)). (c) I-V curve of the ITO/CEA:GQD/Al device when a positive voltage from 0 to 3 V is applied in the 2nd sweep. The inset shows a fitting of the I-V data with a ln (I) versus V0.5 curve for the device under a positive voltage from 0 to 1.3 V (region I in (c)). (d) Fitting of the I-V data with a ln (I) versus ln (V) curve under a positive voltage from 2.3 to 3 V (region II in (c)).
