Bi3+/Mn2+ Codoping Regulates Chloride Vacancies and Self-Trapped Excitons in Cs2ZrCl6 Scintillators.
Lead-free zirconium-based halide scintillators are promising for X-ray detection and imaging owing to their structural stability, defect tolerance, and solution processability. Aliovalent doping can regulate the excited states of vacancy-ordered halide scintillators, but may also generate charge-compensating defects th...
