• • Achieved unprecedented crystallinity of 97.6% in transparent glass-ceramic scintillators via sequential precipitation of CaF2 and BaAl2Si2O8, enabling high performance.
• • Maintains 90.6% of integrated X-ray excited luminescence (XEL) intensity at 300 °C, demonstrating exceptional thermal quenching resistance for high-temperature applications.
• • Integrated XEL intensity reaches 94.2% of commercial BGO at room temperature, indicating competitive scintillation efficiency.
• • Enables stable high-temperature X-ray imaging with spatial resolution of ~10.4 lp mm−1 up to 225 °C, suitable for extreme-environment industrial inspection.
