4 2D distributions of PSD (Qtail/Qtotal) vs Qtotal for the hybrid plastic scintillators with 30 wt% PPO ， 0.2 wt% MDAC and (a) 0 wt% PMMA, (b) 10 wt% PMMA, (c) 20 wt%, (d) 30 wt%. The scintillators were radiated by 238Pu-Be neutron source.

Caption

The excellent separation between neutrons and gamma-rays demonstrates the hybrid plastic scintillators pulse shape discrimination capability between incoming radiation particles. The pulse shape discrimination of the scintillator is not significantly  affected by PMMA within amounts of 30 wt%
