We have developed Bi2O3 nanoparticle-loaded plastic scintillators with high-weight ratio and have measured decay time constant of their scintillation light using SR-X-ray pulse. Detection of less than one scintillation photon per X-ray photon is important when considering the random time interval. We therefore recorded pulse-height spectra with resolving scintillation photon numbers in one X-ray photon detection using a cooled MPPC photodetector.
