Perovskite radiation detection
WebOct 12, 2024 · Recently, metal halide perovskites have received great attention for detecting ionizing radiation. Perovskite-based photodetectors and scintillators have been successfully implemented for X-ray and γ -ray detection due to their high attenuation coefficient and excellent optoelectronic properties. WebThe sensitive X-ray detector was fabricated by depositing 50 nm of gold on both sides of the perovskite crystal. This device exhibited a high sensitivity up to 259.9 μC/Gyair/cm 2 under the 39 keV X-ray exposure at a small electric field of ~0.83 V/mm and yielded a low noise of 3.1 × 10 -23 A 2 /Hz. Additionally, the sensitivity can be ...
