Scintillation materials are sensitive to ionizing radiation<\/strong> and are widely used in various detection systems<\/strong>, including medical imaging<\/strong>, homeland security<\/strong>, high-energy physics (HEP) calorimetry<\/strong>, energy applications<\/strong>, industrial control<\/strong>, oil-well logging<\/strong>, and quantum sensors<\/strong>.<\/p>

Some scintillators exhibit properties enabling applications beyond static radiation imaging \u2014 such as time-of-flight (TOF) measurement<\/strong>, spectroscopy<\/strong>, and ultrafast multi-frame radiation imaging<\/strong>. Two key properties determine their performance: light yield<\/strong> (the number of visible photons produced per unit of deposited radiation energy) and decay time<\/strong> (the speed at which photons are emitted after excitation).<\/p>

Both parameters influence coincidence time resolution (CTR)<\/strong> in positron emission tomography (PET)<\/strong> and output count rate (OCR)<\/strong> in photon-counting computed tomography (PCCT)<\/strong> and fast spectral X-ray imaging<\/strong>. CTR values below 30 ps<\/strong> significantly enhance TOF-PET image quality by improving the signal-to-noise ratio<\/strong>, while OCR > 20 Mcps\/pixel<\/strong> in PCCT would surpass the performance of current CdTe\/CZT semiconductor technologies<\/strong>.<\/p>

The best commercial PET scintillator, Lu\u2082SiO\u2085:Ce (LSO:Ce)<\/strong>, achieves a CTR of 60 ps<\/strong>, but its cost (~426 EUR for a 20\u00d720\u00d720 mm\u00b3 crystal) makes complete TOF-PET systems extremely expensive<\/strong>. Furthermore, progress in PCCT using existing semiconductor technologies is limited due to the need for more stable and reliable detectors<\/strong>.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Inspired by advances in photovoltaics<\/strong>, this project proposes solution-processable perovskite scintillators<\/strong> as a cost-effective alternative<\/strong> to LSO:Ce \u2014 potentially reducing costs by a factor of up to 50<\/strong>. Two promising candidates are:<\/p>

  • 2D hybrid organic\u2013inorganic perovskite crystals (2D HOIP)<\/strong><\/p><\/li>

  • Lead-free all-inorganic perovskite crystals (AIP)<\/strong><\/p><\/li><\/ul>

    Current 2D HOIP scintillators exhibit a light yield >20 photons\/keV<\/strong> and decay times <5 ns<\/strong>, resulting in a CTR of about 80 ps<\/strong> \u2014 slightly inferior to LSO:Ce but with an absorption length only four times greater<\/strong>. Lead-free AIP crystals, with an absorption length comparable to LSO:Ce, achieve up to 100 photons\/keV<\/strong>, yet their decay times (~50 ns)<\/strong> yield CTR values exceeding 150 ps<\/strong>.<\/p>

    To achieve the target 30 ps CTR<\/strong>, the light yield<\/strong> of 2D HOIP and AIP scintillators must be enhanced three- to fivefold<\/strong>. For PCCT, current 2D HOIP crystals already reach 10 Mcps\/pixel<\/strong>, only two times lower than state-of-the-art semiconductor technology.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

    The Fapurite project<\/strong> aims to overcome these limitations by employing nanophotonics<\/strong>, specifically resonant nanostructures<\/strong>, to enhance light emission through the Purcell effect<\/strong>. This approach will simultaneously improve light yield<\/strong> and decay time<\/strong>, enabling a reduction in CTR<\/strong> and an increase in OCR<\/strong>, paving the way for faster and more efficient perovskite-based scintillators<\/strong> for advanced imaging technologies.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
