Carbon Dots as Afterglow Scintillators for Ultralong Afterglow and Low‐Dose X‐Ray Imaging

. Based on these x-ray excitation radiation luminescence characteristics of TpB-CDs@Urea composites, their potential applications in x-ray photography technology were also demonstrated. Ultimately, the findings of this study provide a feasible principle for designing high-performance afterglow scintillator materials while expanding their application in fields such as detection and x-ray radiography.
