title = "Development of plastic scintillators loaded with perovskite quantum dots",
abstract = "We developed plastic scintillators loaded with perovskite quantum dots (QDs) to enhance the detection efficiency for high-energy photons such as X-rays and gamma rays. QDs with different emission wavelengths were loaded onto plastic scintillators at 5 wt%. The emission from the QDs only was observed in the radioluminescence spectra under X-ray irradiation. The photoluminescence decay behavior indicates that the absorption of the QD emission by the QDs themselves (self-absorption) results in long decay components, which were also observed in the scintillation decay. The detection efficiency for 67.4 keV X-rays was successfully enhanced by loading, although the scintillation light yield was reduced. ",
