Outline of Final Research Achievements |
There is an increasing demand for fast-response detectors for high-energy X-ray photons from synchrotron radiation sources. In this study, we developed fast scintillators based on plastic scintillators incorporated with nanoparticles of heavy element oxides. By the incorporation, the detection efficiency of the plastic scintillators was significantly enhanced. The hybridization of plastic scintillators with nanoparticles synthesized via supercritical hydrothermal route enables the fabrication of fast scintillators for specific X-ray energy regions.
