Název v původním jazyce

Achieving efficient neutron and gamma discrimination in a highly stable 6Li-Loaded Cs3Cu2I5 perovskite scintillator

Popis výsledku v původním jazyce

Low-dimensional Cu(I) perovskite halides with efficient exciton emissions have recently emerged as promising scintillation materials for X-ray and gamma-ray detection applications. Here, we demonstrate the possibility of using zero-dimensional Cs3Cu2I5 for the sensitive detection of thermal neutrons and neutron−gamma discrimination enabled by Li doping. Single crystals of Cs3Cu2I5 doped with 95% enriched 6Li were grown by the Bridgman method. Cs3Cu2I5:6Li offers a compelling combination of high stability against moisture and oxygen, a decent energy resolution of 4.8% for 662 keV 137Cs gamma-rays, a high light yield of 30 000 photons/MeV for gamma-rays, and 96 000 photons/neutron for thermal neutron, and a good neutron−gamma pulse shape discrimination figure of merit of 2.27. Our discovery of 6Li-doped low-dimensional perovskite halides opens up a new horizon for stable and high-performance neutron−gamma scintillator design.
