Two dimensional plots of PSP versus light output for the 1″ samples (aged 3 m) with different wt% PPO and of EJ-212 under irradiation with Pb shielded 252Cf source; the evaluated FoM at the threshold 480 ± 75 keVee, shown in each plot as a dashed line, is also reported for each scintillator and listed in Table 3.
