There is an increasing demand for the development of detectors with high detection efficiency and high-speed response in high-count measurement of high-energy radiation in synchrotron radiation facilities. Although plastic scintillators (PS) have been studied for a long time, the problem of insufficient detection efficiency remains unsolved. In this study, we investigated the high-energy photon detection characteristics when different phosphors were used.
