Organic Scintillators Containing HighZ Nanoparticles

The light yield produced from the PMT is low, and thus the gamma photoelectron energy resolution is low. Scintillation solution loaded with hafnium oxide nanoparticles emitting blue light was then prepared. At 50 wt% loading of the nanoparticles, the transmittance at the emission peak wavelength is still higher than 80%.
