Deciphering the mechanism of ultrafast scintillation in 1D silver halides
Original language description
The development of ultrafast scintillators is critical to the GHz X‐ray and time‐of‐flight (TOF) imaging techniques. Low‐dimensional silver‐based halides have emerged as promising candidates due to high radioluminescence efficiency and ultrafast decay time. However, the ultrafast scintillation mechanism in silver‐based halides, such as Rb2AgBr3 (RAB), remains controversial. Here, the study reveals the origin of ultrafast scintillation timing response in melt‐grown RAB bulk crystals. The RAB shows light‐yellow emission with a photoluminescence quantum yield (PLQY) of 13.9%. Under the picosecond (ps) pulse X‐ray irradiation, RAB has an ultrafast decay time of 3.2 ns that accounts for 40.5% of the total emitted light. The light yield is estimated as 3100 photons MeV⁻¹ under ²²Na irradiation.
