Abstract

We attempted to enhance the detection efficiency of plastic scintillators by incorporating zirconia nanoparticles up to 30 wt%. The scintillators became opaque at higher concentrations because of Mie scattering. A higher nanoparticle concentration led to a higher detection efficiency, and the light yield of these scintillators was higher than or comparable to that of a commercial plastic scintillator, NE142. In addition, the time resolution of the scintillation detector equipped with each sample scintillator was approximately 0.5 ns. These results indicate that the incorporation of nanoparticles is a versatile and effective approach to enhance the detection efficiency of plastic scintillators.
