- Abstract
- Readily commercializable and cost-effective next-generation CsPbBr3 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 (approximate to 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 = approximate to 1200 ns) because the PNCs-based scintillator has approximate to 5.6-fold faster average photoluminescence lifetime and stronger emission than the GOS-based one.
