Figure 3.
Lower panel: Exciplex emission decays of the 9,10-dimethylanthracene (10–5 M)/N,N-dimethylaniline (0.05 M) system in pure butyronitrile at εr = 24.3 in the presence and absence of an external magnetic field (ca. 150 mT) observed with a long-pass filter (>600 nm) after excitation at 395 nm. In the presence of an external magnetic field, the delayed fluorescence of the exciplex is enhanced. Upper panel: Time-resolved magnetic field effect ΔI obtained by taking the difference of the experimental single photon timing traces recorded in the presence and absence of an additional external magnetic field (gray) and the fit to the experimental data (black).
