Abstract

X-ray detection is indispensable in medical imaging, security inspection, and scientific research. Green lead-free perovskites have a great prospect in the field of X-ray detection. Herein, a new layered hybrid double perovskite (I-BA)₄AgBiI₈ (IAB, I-BA⁺ is I-n-butylammonium) was rationally designed. Strikingly, it had a large μτ product up to ∼2.28 × 10⁻³ cm² V⁻¹ and showed an X-ray response with a superior sensitivity of 5.38 μC Gy_air⁻¹ cm⁻².
