Abstract
Readily commercializable and cost-effective next-generation CsPbBr 3 perovskite nanocrystals (PNCs) based X-ray detectors are demonstrated. The PNCs-based X-ray detector exhibits higher spatial resolution (9.8 lp mm −1 at modulation transfer function (MTF) = 0.2 and 12.5–8.9 lp mm −1 for a linear line chart), faster response time (≈200 ns), and comparable stability (>40 Gy air s −1 of X-ray exposure) compared with the commercialized terbium-doped gadolinium oxysulfide (GOS)-based detectors (spatial resolution = 6.2 lp mm −1 at MTF = 0.2 and 6.3 lp mm −1 for a linear line chart, response time = ≈1200 ns) because the PNCs-based scintillator has ≈5.6-fold faster average photoluminescence lifetime and stronger emission than the GOS-based one.
