WebIt is shown that balanced electron and hole mobility is a critical criterion for faster speed OPDs, which can be realized by tuning the composition ratio of the bulk heterojunction. By tuning PTNT and PC71BM blend ratio, the f–3dB was successfully raised by more than quadruple to 4.5 MHz. WebWe explain this higher performance to the significant enhancement of hole charge mobility, predicted by means of the Trap Charge Limited Current (TCLC) model. Moreover, because of the color combination and taking advantage of the PFO deep-blue emission and BTS emission involving the ESIPT process, white-light emission was produced in a single ...
