[PMID: 38629161 PMCID: PMC11061828 DOI: 10.1021/acs.inorgchem.4c00809] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2024] [Revised: 04/04/2024] [Accepted: 04/09/2024] [Indexed: 04/30/2024]
Abstract
We report high-pressure single-crystal X-ray diffraction, optical absorption, and photoluminescence investigations of all-inorganic perovskite-related materials CsPb2Cl5 and Cs4PbCl6. The crystal structure of CsPb2Cl5, composed of alternate layers of Cs+ cations and Pb-Cl frameworks, is stable under pressure up to at least 4.2 GPa. Because external stress is mainly absorbed by the Cs+ layers, the optical absorption edge of the crystal only slightly red-shifts with increasing pressure, which correlates well with a moderate shortening of the Pb-Cl bonds. A quite different response to pressure shows Cs4PbCl6, the crystal built of isolated PbCl64- octahedra and Cs+ cations. During the compression at around 3.4 GPa, the trigonal phase I, space group R3̅c, transforms to the orthorhombic phase II, space group Cmce, which at around 4 GPa transforms into phase III. On decompression, phase II is not restored, but phase III converts through a diffuse phase transition into another high-pressure phase IV, which is stable in a wide pressure range and transforms to the initial phase I only around atmospheric pressure. The red shift of the absorption edge and the profound modification of the absorption spectrum in phase II were ascribed to the deformation of the PbCl64- octahedra. The transition to phase III induces a blue shift of the absorption edge, while the transition to phase IV is associated with a large red shift. Photoluminescence was detected in phases I and II with the intensity quenched with increasing pressure.

Abstract
All-inorganic perovskites have garnered significant attention in optoelectronics. Herein, square CsPb2Br5 nanosheets, with lateral dimensions of up to 200 μm and a thickness of less than 50 nm, were successfully synthesized via a straightforward aqueous method using HBr as a morphology-tailoring agent. A photodetector composed of a single nanosheet was subsequently fabricated and exhibited remarkable photodetection capabilities, demonstrating a detectivity of 5.98 × 109 Jones. These findings offer new perspectives on the synthesis and utilization of CsPb2Br5 and other perovskite nanostructures in optoelectronic devices.

Abstract
All-inorganic lead halide perovskite has emerged as an attractive semiconducting material due to its unique optoelectronic properties. However, its poor environmental stability restricts its broad application. Here, a simple method for the fabrication of CsPb2Br5/TiO2 is investigated. The introduction of p-aminobenzoic acid, which has two functional groups, is critical for the capping of amorphous TiO2 on CsPb2Br5. After calcination at 300 °C, amorphous TiO2 crystallizes into the anatase phase. The CsPb2Br5/TiO2 NCs show high long-term stability in water and enhanced stability against ultraviolet radiation and heat treatment, owing to the chemical stability of TiO2. More importantly, photo-electrochemical characterizations indicate that the formation of TiO2 shells can increase the charge separation efficiency. Hence, CsPb2Br5/TiO2 exhibits improved photoelectric activity owing to the electrical conductivity of the TiO2 in water. This study provides a new route for the fabrication of optoelectronic devices and photocatalysts based on perovskite NCs in the aqueous phase. Furthermore, the present results demonstrate that CsPb2Br5/TiO2 NCs has considerable potential to be used as a photoelectric material in optical sensing and monitoring.

Abstract
![]()
CsPb2Br5 belongs to all inorganic
perovskite-related
quasi-two-dimensional materials that have attracted considerable attention
due to their potential for optoelectronic applications. In this study,
we solve numerous controversies on the physical properties of this
material. We show that optical absorption in the visible spectrum
and green photoluminescence are due to microcrystallites of the three-dimensional
CsPbBr3 perovskite settled on the CsPb2Br5 plates and that carefully cleaned crystal plates are devoid
of these features. The high-pressure structural and spectroscopic
experiments, performed on the single crystals free of CsPbBr3 impurities, evidenced that the layered tetragonal structure of CsPb2Br5 is stable at least up to 6 GPa. The absorption
edge is located in the ultraviolet at around 350 nm and continuously
red shifts under pressure. Moderate band gap narrowing is well correlated
to the pressure-induced changes in the crystal structure. Although
the compressibility of CsPb2Br5 is much higher
than for CsPbBr3, the response in optical properties is
weaker because the Pb–Br layers responsible for the optical
absorption are much less affected by hydrostatic pressure than those
built of Cs+ cations. Our study clarifies the confusing
data in the literature on the optical properties and thermodynamic
stability of CsPb2Br5. The impact of genuinely hydrostatic pressure on the structure
and optical properties of pure CsPb2Br5 was
studied for the first time on single crystals. The results provide
new information about the crystal stability, photoluminescence, and
optical absorption.

Abstract
Conversion of CO2 into valuable chemical feedstocks through artificial photosynthesis is an effective strategy to alleviate energy and environmental issues. Herein, we have developed a novel perovskite-based catalyst via in situ growing CsPbBr3 quantum dots (QDs) on the affinal 2D CsPb2Br5 nanosheets for CO2 photoconversion. CsPbBr3 QDs were generated by peeling off layers from their cubic counterpart; meanwhile, CsPb2Br5 nanosheets were formed by heaping up the peeled layers. The resultant dual-phase composite exhibited outstanding activity and selectivity for photocatalytic conversion of gaseous CO2 with a CO generation rate of 197.11 μmol g-1 h-1 under 300 W Xe lamp irradiation, which is 2.5 and 1.1 times higher than that of pure CsPb2Br5 or CsPbBr3. Importantly, the fabricated dual-phase material presented extremely high stability and was able to maintain an unchangeable CO2 conversion rate under wet air in the consecutive 10 h of recycling test. Furthermore, attributing to the in situ assembling strategy, the close contact allowed photo-generated electrons in CsPbBr3 QDs to transfer rapidly to CsPb2Br5, and the affluent active sites in such an architecture enabled achieving enhanced CO2 photoconversion activity. The present work provides an attractive approach for in situ constructing a consubstantial perovskite-based composite photocatalyst to ensure great stability and excellent activity for artificial photocatalytic CO2 conversion.

Abstract
Chemical transformation of typically "nonlayered" phases into two-dimensional structures remains a formidable task. Among the thickness tunable CsPbX3 (X = Br, Br/I, I) nanosheets (NSs), CsPbBr1.5I1.5 NSs with a thickness of ∼4.9 nm have structural stability superior to ∼6.8 nm CsPbI3 NSs and better hole mobility than ∼3.7 nm CsPbBr3 NSs. Moving beyond the much-explored CsPbBr3 photodetectors, we demonstrate a sharp improvement of the photodetection of CsPbBr1.5I1.5 NS devices by thickening the NSs to ∼6.1 nm through combining 8-carbon and 18-carbon ligand surfactants. Thereby, the responsivity increases up to one of the highest values of 3313 A W-1 at 1.5 V (and 3946 A W-1 at 2 V) with detectivity of 1.6 × 1011 Jones at 1.5 V, due to the increase in carrier mobility up to 7.9 × 10-4 cm2 V-1 s-1. The better device performance of the NSs than 8.6-13.9 nm nanocubes (NCs) is due to their planarity which facilitates in-plane mobilization of the charge carriers.

Abstract
Lead halide perovskite (LHP) nanomaterials have attracted tremendous attention owing to their remarkable optoelectronic properties. However, they are extremely unstable under moist environments, high temperatures, and light illumination due to their intrinsic structural lability, which has been the critical unsolved problem for practical applications. To address this issue, we propose a facile and environmentally friendly ligand-free approach to design and synthesize rod-like CsPb2Br5-embedded Pb(OH)Br with excellent stability under various harsh environments such as soaking in water, heating, and ultraviolet (UV) illumination. Plate-like CsPbBr3- and Cs4PbBr6-embedded Pb(OH)Br powders are first formed by evaporating the solvent in a dispersion of ethanol (or methanol, isopropanol), Cs2CO3, and PbBr2. Upon soaking in water, the plate-like sample undergoes phase transformation from CsPbBr3 and Cs4PbBr6 to CsPb2Br5 and shape conversion from nanoplate to a microrod, leading to the formation of rod-like CsPb2Br5-embedded Pb(OH)Br. The stable Pb(OH)Br coating effectively prevents the luminescent CsPb2Br5 nanocrystals from reacting with water, leading to extremely high aqueous stability of the CsPb2Br5-embedded Pb(OH)Br. The photoluminescence (PL) intensity of the representative CsPb2Br5-embedded Pb(OH)Br sample can maintain 92.2% of the initial PL intensity value even after soaking in room-temperature water for 165 days; in the meantime, the phase and shape are preserved. The typical sample also shows outstanding stability under hot water, UV illumination, and annealing conditions. The ultrahigh aqueous stability, thermal stability, and photostability of the CsPb2Br5-embedded Pb(OH)Br nanomaterials suggest an effective, facile, and environmentally friendly technique to grow perovskite-based nanomaterials for promising practical applications in the optoelectronic field.
