Stable and highly sensitive self-powered X-ray detection <i>via</i> high-density CsPbBr-type Dion-Jacobson trilayer hybrid perovskites.

ABSTRACT: Dion-Jacobson (DJ)-type organic-inorganic hybrid perovskites have emerged as promising candidates for X-ray detection owing to their exceptional stability and remarkable X-ray absorption ability. Nevertheless, achieving enhanced detection sensitivity continues to pose a significant challenge in this research domain. Herein, we have successfully synthesized and grown a DJ-type (4-AMP)Cs₂Pb₃Br₁₀ (1, 4-AMP²⁺ = 4-ammoniomethylpiperidinium) hybrid perovskite single crystal with a high density of 3.966 g cm^-3. This density value is the highest reported value in DJ-type hybrid perovskite materials to date. Benefiting from its high density that provides strong X-ray absorption capability, 1 exhibits excellent X-ray detection performance under
