Extended Data Fig. 7: RL linear relationships of TADF organic scintillators.

The RL intensities versus biggish X-ray dose rates of DMAc-TRZ, 4CzIPN and 4CzTPN-Bu, respectively. The error bars were determined by the measurements of three samples and each sample was measured three times. It can be obviously observed that these TADF organic scintillators show good linear relationships between RL intensity and X-ray dose rate. (X-ray tube voltage: 50 kV, current: 79 μA).
