摘要
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.
