Title: Lead-free halide double perovskite-polymer composites for flexible X-ray imaging

Abstract

X-ray detectors are demonstrated using composite films of lead-free Cs₂AgBiBr₆ halide double perovskite embedded in a polymer matrix as the X-ray photoconductors. Polymers with hydroxyl functional groups greatly improve the uniformity of the composite films, and large area dense films are obtained using a simple drop-casting process. X-ray detectors based on the composite films exhibit a sensitivity of 40 μC Gy_air^-1 cm^-2, comparable to the reported sensitivity using Cs₂AgBiBr₆ single crystals. Such detectors can also tolerate a 5% tensile/compressive strain in the composite films without performance degradation. Pixelated X-ray detectors fabricated on the same composite film can realize X-ray imaging and resolve a proof-of-concept geometric pattern.

Impact of processing conditions on the film formation of lead-free halide double perovskite Cs₂AgBiBr₆

Journal Article Abdelsamie, Maged ; Cruse, Kevin ; Tamura, Nobumichi ; ... - Journal of Materials Chemistry. A

Lead-free halide double perovskites with enhanced stability have gained attention as a promising environmentally friendly alternative to lead-based halide perovskites. Amongst different halide double perovskites, Cs₂AgBiBr₆ has shown attractive optoelectronic properties and stability, making it a promising candidate for stable high-efficiency optoelectronic devices. Motivated by a data mining effort, we present here in this study the effects of different processing strategies on the microstructure and thin-film formation dynamics of Cs₂AgBiBr₆. We apply some of the most successfully used solvent engineering approaches from the halide perovskite research to halide double perovskites, namely antisolvent- and additive-assisted synthesis.

Nucleation-controlled growth of superior lead-free perovskite Cs₃Bi₂I₉ single-crystals for high-performance X-ray detection

Journal Article Zhang, Yunxia ; Liu, Yucheng ; Xu, Zhuo ; ... - Nature Communications

The organic-inorganic hybrid lead halide perovskites have emerged as a series of star materials for solar cells, lasers and detectors. However, the issues raised by the toxic lead element and marginal stability due to the volatile organic components have severely limited their potential applications. In this work, we develop a nucleation-controlled solution method to grow large size high-quality Cs₃Bi₂I₉ perovskite single crystals (PSCs). Using the technique, we harvest some centimeter-sized single crystals and achieved high device performance. We find that X-ray detectors based on PSCs exhibit high sensitivity of 1652.3 μC Gy_air^-1 cm^-2and very low detectable dose rate of 130more »« less

Pressure‐Induced Emission (PIE) and Phase Transition of a Two‐dimensional Halide Double Perovskite (BA) ₄ AgBiBr ₈ (BA=CH ₃ (CH ₂ ) ₃ NH ₃ ⁺ )

Journal Article Fang, Yuanyuan ; Zhang, Long ; Wu, Lianwei ; ... - Angewandte Chemie

Abstract Two‐dimensional (2D) halide perovskites have attracted significant attention due to their compositional flexibility and electronic diversity. Understanding the structure–property relationships in 2D double perovskites is essential for their development for optoelectronic applications. In this work, we observed the emergence of pressure‐induced emission (PIE) at 2.5 GPa with a broad emission band and large Stokes shift from initially nonfluorescent (BA) ₄ AgBiBr ₈ (BA=CH ₃ (CH ₂ ) ₃ NH ₃ ⁺ ). The emission intensity increased significantly upon further compression up to 8.2 GPa. Moreover, the band gap narrowed from the starting 2.61 eV to 2.19 eV at 25.0 GPa accompanied by a colormore »« less

Chemical and Structural Diversity of Hybrid Layered Double Perovskite Halides

Journal Article Mao, Lingling ; Teicher, Samuel M. L. ; Stoumpos, Constantinos C. ; ... - Journal of the American Chemical Society

Hybrid halide double perovskites are a class of compounds attracting growing interest due to their richness of structure and property. Two-dimensional (2D) derivatives of hybrid double perovskites are formed by the incorporation of organic spacer cations into three-dimensional (3D) double perovskites. Here, we report a series of seven new layered double perovskite halides with propylammonium (PA), octylammonium (OCA), and 1,4-butyldiammonium (BDA) cations. The general formulas of the compounds are A_mM^IM^IIIX₈ (single-layered Ruddlesden–Popper type with m = 4 and A = PA or OCA, and single-layered Dion–Jacobson type with m = 2 and A = BDA, M^I = Ag, M^III= Inmore »« less
