Abstract

Halide perovskite semiconductors are poised to revitalize the field of ionizing radiation detection as they have done to solar photovoltaics. We show that all-inorganic perovskite CsPbBr₃ devices resolve ¹³⁷Cs 662-keV γ-rays with 1.4% energy resolution, as well as other X- and γ-rays with energies ranging from tens of keV to over 1 MeV in ambipolar sensing and unipolar hole-only sensing modes with crystal volumes of 6.65 mm³ and 297 mm³, respectively. We report the scale-up of CsPbBr₃ ingots to up to 1.5 inches in diameter with an excellent hole mobility–lifetime product of 8 × 10⁻³ cm² V⁻¹ and a long hole lifetime of up to 296 μs. CsPbBr₃ detectors demonstrate a wide temperature region from ~2 °C to ~70 °C for stable operation. Detectors protected with suitable encapsulants show a uniform response for over 18 months. Consequently, we identify perovskite CsPbBr₃ semiconductor as an exceptional candidate for new-generation high-energy γ-ray detection.
