Figure 2

(a) The PL efficiencies of the films of mCP: fluorophors: EHA perturbers. (b) The Stern–Volmer plots for quenching of these fluorophors by EHA perturbers. F0 stands for the PL efficiency of the fluorophors without EHA perturbers while F is the PL efficiency with EHA perturbers. (c) The transient decay curves of films of mCP: Bebq2: Ir(ppz)3 measured at 490 nm with an excitation wavelength of 430 nm. (d) The transient decay curves of films of mCP: t-Bu4CzTPN: Firpic measured at 576 nm with an excitation wavelength of 490 nm. EHA, external heavy-atom effect; PL, photoluminescence.
