Next-generation scintillators based on quantum dots

Scintillators are materials that emit visible light when absorbing high-energy ionizing radiation (e.g. X-rays). Scintillation detectors are the core of radiation detection applications in medical imaging (e.g., X-ray Radiography, Computed Tomography, Positron Emission Tomography), homeland security (e.g. luggage and cargo screening, detection of fissile materials), high energy physics (e.g. Higgs boson discovery at LHC, CERN), and many more. Lead halide perovskites show bright and fast emission, crucial for modern scintillators, and may be the candidates for next-generation detectors. Moreover, recently an ultra-fast collective emission under X-ray excitation was demonstrated from CsPbBr3 superlattices [1], promising a breakthrough in scintillation science.
