a Emission and (b) XRD spectra of p-Br-TRZ (solid powder) recorded at 25 °C upon different heating treatments for 5 min at 25 (black line, no heating), 70 (blue line), 100 (green line), 130 (orange line), and 150 °C (red line), respectively. c Emission spectra obtained before and after UV irradiation (365 nm LED, 516 mW/cm2) for 90 s at −40 °C.
