Scintillation properties of flexible scintillator composed on polydimethylsiloxane integrated with Lu2GdAl3Ga2O12:Pr2O3 phosphors

초록

This study explored the luminescence properties and sensitivity of a flexible scintillator composed on polydimethylsiloxane integrated with Lu2GdAl3Ga2O12 doped with 1 mol% Pr2O3 phosphors. The flexible scintillator was fabricated using a molding technique. The luminescence properties were investigated under photo, proton, and X-ray excitation at room temperature. The scintillator exhibited sharp and narrow emission peaks attributed to f-f transitions, and a decay time of 14 mu s. It demonstrated a sensitivity of 0.638 mu C/R & sdot;cm 3 under an X-ray dose of 1.841 R. This study demonstrates a high performance flexible scintillator suitable for advanced radiation detection applications in medical imaging and safety monitoring.
