Recently, the utilization of metal halide perovskites in sensing and their application environmental studies have reached a new height. Among different perovskites, cesium lead (CsPbX3; X = Cl, Br, I) composites attracted great interest applications owing to exceptional optoelectronic properties. Most CsPbX3 nanostructures possess structural stability, luminescence, electrical properties for developing distinct optical photonic devices. When exposed light, heat, water, can display stable utilities. Many been reported as probes detection diverse analytes, such ions, anions, important chemical species, humidity, temperature, radiation photodetection, so forth. So far, covering all metallic organic–inorganic already reviewed many studies. Nevertheless, detailed review utilities could be helpful researchers who are looking innovative designs using these nanomaterials. Herein, we deliver thorough composites, quantitation chemicals, explosives, bioanalytes, pesticides, fungicides, cellular imaging, volatile organic compounds (VOCs), toxic gases, radiation, photodetection. Furthermore, this also covers synthetic pathways, design requirements, advantages, limitations, future directions material.

Inorganic Chemistry, Год журнала: 2024, Номер 63(16), С. 7422 - 7429

Опубликована: Апрель 10, 2024

Eco-friendly halide double perovskites are attracting significant attention as potential substitutes for traditional lead-based perovskites. However, their typically wide or indirect band gap limits further technological advancement. This study presents a new, eco-friendly, all-inorganic millimeter-scale CsCuAgI3 single crystal (SC). The exhibits direct of 2.02 eV at the G-point, markedly superior to that absorption and photoluminescence spectra corroborate its attributes. Owing B-site Cu–Ag disorder, possesses higher Urbach energy (119 meV), indicative structural disorder. Stokes shift 230 nm, full width half-maximum (fwhm) 152 long fluorescence lifetime 7.29 μs, excellent stability. In addition, photoelectric detection prototype was prepared using crystal. Using 375 nm laser excitation source, device showed very sensitive response, clocking in (0.37/0.21) seconds. work offers new insights into developing novel lead-free perovskite crystals exploring applications.
