Fig. 1 (a) Steady-state UV-Vis absorption and photoluminescence (PL) emission spectra obtained in degassed toluene at room temperature. (b) Time-resolved PL spectra recorded in a closed cryostat at different temperatures. Excitation was provided by a 360 nm laser, with delay and gate times indicated. The steady-state PL spectrum (gray) was measured under ambient conditions. The doping concentration of the model emitter in PMMA is 2 wt%. (c) Temperature dependent transient PL decay of 1.8-mDTAZ-PhtCz (10 wt%) doped in PMMA. Here, the PL decay was measured by an iCCD camera, with the measurement condition summarized in the experimental section. (d) Intramolecular interactions of the model compound in the single crystal. (e) Ultralong afterglow emission from the model emitter 1.8 mDTAZ-PhtCz crystal.
