Abstract :

The influence of hydrogen bonding on spectroscopic properties is one of the fundamental issues in the field of luminescent organic-inorganic hybrid metal halides (OIMHs). We design and prepare three OIMHs, namely, crystals 1, 2 and 3, using 2,2 '-bipyridine and ZnCl2 as starting materials. From crystals 1 to 3, the hydrogen bonding environment surrounding the 2,2 '-bipyridinium cations gradually weakens, with both the dihedral angle and the number of hydrogen bonds around them decreasing progressively. Correspondingly, the blue emission belonging to the S1 -> S0 transition of the three crystals gradually increases, with crystal 3 exhibiting the strongest blue light emission and a photo-luminescence quantum yield reaching 34.10%. In crystal 1, the dense hydrogen bonding environment of the 2,2 '-bipyridinium cation results in an obvious energy transfer from S1 to T1. This reduces the population of the S1 state, thereby leading to weaker blue light emission. In crystals 2 and 3, the weaker hydrogen bonding environment and smaller spatial distortion of organic cations weaken or even prevent energy transfer between S1 and T1, thereby enhancing blue light emission. These findings provide new insights for exploring novel luminescent OIMHs and developing more effective means of regulating their luminescence performance.

Abstract :

Heterojunction photocatalysts, which consist of two or more semiconductors, have garnered significant attention owing to their extensive benefits, including a broad-spectrum response, efficient carrier separation and migration, as well as robust redox capabilities. Among the myriad of semiconductors, graphitic carbon nitride (g-C3N4) and zinc indium sulfide (ZnIn2S4) have been extensively researched due to their low toxicity, straightforward and scalable synthesis processes, controllable microstructures, and exceptional chemical stability. Recently, there has been a trend towards integrating these two semiconductors to complement each other's strengths. Consequently, a systematic summary and outlook on g-C3N4/ZnIn2S4 heterojunction photocatalysts is both urgent and valuable. This review summarizes the advancements in the g-C3N4/ZnIn2S4 heterojunctions in the last 10 years. We first analyzed the charge-transfer mechanisms in the type-I, type-II, Z-scheme and S-scheme heterojunctions. Then the typical synthesis methods employed for creating g-C3N4/ZnIn2S4 heterojunctions are introduced. Subsequently, we delve into the regulation strategies for g-C3N4/ZnIn2S4 heterojunctions, including morphology optimization, heteroatom doping, defect engineering, and the construction of multinary composites. The design concept and superiorities of these strategies are thoroughly discussed. Following this, we systematically showcase the photocatalytic applications of g-C3N4/ZnIn2S4 heterojunctions, encompassing CO2 reduction, H2 evolution, pollutant degradation, H2O2 production, biomass conversion, photoelectrochemical sensors, and so forth. Last, we propose the challenges that lie ahead in future research endeavors. This comprehensive review is expected to provide an instructive guideline for rational design and applications of g-C3N4/ZnIn2S4 heterojunctions.

Abstract :

Birefringent crystals play an irreplaceable role in optical systems by adjusting the polarization state of light in optical devices. This work successfully synthesized a new thiophosphate phase of B-Pb3 P2 S8 through the high-temperature solid-state spontaneous crystallization method. Different from the cubic a-Pb3 P2 S8 , the B-Pb3 P2 S8 crystallizes in the orthorhombic Pbcn space group. Notably, B-Pb3 P2 S8 shows a large band gap of 2.37 eV in lead-based chalcogenides, wide infrared transparent window (2.5-15 mu m), and excellent thermal stability. Importantly, the experimental birefringence shows the largest value of 0.26@550 nm in chalcogenides, even larger than the commercialized oxide materials. The Barder charge analysis result indicates that the exceptional birefringence effect is mainly from the Pb2 + and S2- in the [PbSn ] polyhedrons. Meanwhile, the parallelly arranged polyhedral layers could improve the structural anisotropic. Therefore, this work supports a new method for designing chalcogenides with exceptional birefringence effect in the infrared region.

Abstract :

In this study, divalent calcium cation with large radius and trivalent yttrium cation with small radius were introduced to develop co-stabilized zirconia ceramics with both superior mechanical properties and aging resistance. Through a reverse coprecipitation-hydrothermal method, a series of ultrafine xCaO-yY2O3-ZrO2 (x = 2.0, 3.0, y = 0.5, 1.0, 1.5, 2.0) raw powders with high quality were fabricated for the production of nanostructured ceramics via low-temperature pressurelessly sintering. The sintering process was optimized by investigating the effects of sintering temperature on densification, grain growth and phase evolution. The minimally doped 2.0CaO-0.5Y2O3-ZrO2 ceramic retained pure tetragonal phase at room temperature, achieving a balance of excellent toughness and high aging resistance. The impacts of chemical composition on microstructure, hardness, toughness and aging resistance were examined for these xCaO-yY2O3-ZrO2 (x = 2.0, 3.0, y = 0.5, 1.0, 1.5, 2.0) ceramics. The segregation of calcium and yttrium cations at grain boundaries effectively tailored the microstructure. It was observed that substituting small trivalent yttrium cations for large divalent calcium cations effectively enhanced the aging resistance without sacrificing mechanical properties, due to the strengthened grain boundaries and asymmetrical distribution of cations among grains. This work not only produces low-doped zirconia ceramics with both excellent mechanical properties and aging resistance, but also presents straightforward method for preparation of high-quality raw powders and delicate microstructural engineering during sintering for developing advanced structural ceramics. © 2025 Elsevier Ltd and Techna Group S.r.l.

Abstract :

Studying lithium growth on diverse substrates with unique crystal structures is crucial for linking atomic and macroscopic views, which ensures a long cycle life and safety in lithium metal batteries. This work provides explanations on (1) the stages of nucleation, which are influenced by the adsorption-relaxation mechanism, (2) acquiring evolved traits of dendritic morphology from the embryo, and (3) the integration of the atomic and macroscopic perspectives through a variety of techniques at different scales to validate dendrite evolution. The heteroepitaxial growth process of the embryos is divided into two principal stages: nucleation and growth. The adsorption-type substrates exhibit characteristics of relatively lower average interaction energy and specific stress energy during the nucleation stage. At the growth stage, the adsorption-type substrate tends to facilitate multilayer growth. This work provides potential to design and material selection for lithium metal batteries, contributing to the development of safer, more efficient, and longer-lasting energy storage systems.

Tailoring the π-π stacking interaction among organic cations in hybrid metal halide crystals towards tunable light emission SCIE

Abstract :

As an important interaction among organic cations containing aromatic rings, the pi-pi stacking interaction is a crucial factor determining the crystal structure of organic-inorganic hybrid metal halides (OIMHs). However, the relationship between pi-pi interaction and optical properties of luminescent OIMHs is yet to be studied. (C10H10N2)Cd1-xZnxCl4 (23-Cd1-xZnxCl4) crystals with 0D structures are synthesized by using optically active 2,3 '-bipyridine as the organic ligand. When x <= 0.2, there is no pi-pi interaction among 2,3 '-bipyridinium cations in 23-Cd1-xZnxCl4 crystals. When x > 0.2, pi-pi interaction among organic cations occurs and enhances as the Zn2+ content increases. The tailoring of the pi-pi interaction endows 23-Cd1-xZnxCl4 with tunable light emitting properties, resulting in a broad band emission involving blue and orange species. The blue emission dominates when there is no pi-pi interaction, while the orange emission enhances and finally becomes dominant as the strength of pi-pi interaction increases. The pi-pi interaction promotes the energy transfer from the higher energy valley to the lower one of the S-1 state of the organic cation, resulting in the enhancement of orange emission. Notably, the 23-ZnCl crystal exhibits a photo-luminescence quantum yield (PLQY) of 32%. This is the highest reported value to date among the Zn-based OIMHs, which have optical emission originating from the organic component. The mechanism of pi-pi stacking induced tunable light emission revealed in our work provides new guidance for the design of luminescent OIMHs.

Abstract :

As a class of emerging photoluminescent materials, hybrid halide crystals have drawn research attention for their potential application in the fields of light-emitting, security, and waveguide. Nevertheless, hybrid halide crystals containing antimony with long-term stability and tunable light emission are still increasingly in demand. In this work, serial new hybrid halide crystals (BZA)(2)ZnCl42H(2)O:xSb(3+) (x = 0-0.2, x represents the reaction ratio) and (BZA)(2)SbCl5 are synthesized (BZA = 2,4-diamino-6-phenyl-1,3,5-triazine). In (BZA)(2)ZnCl42H(2)O:xSb(3+) crystals, Sb3+ cations replace partial Zn2+ cations to form [SbCl4](-) tetrahedron. Red light emission caused by the substitution of Sb3+ for Zn2+ enhances as the doping rate increases, resulting in the tunable emission from light blue to pink and finally to dark red. There are two kinds of Sb3+ in (BZA)(2)SbCl5 crystal. Sb(1) has a sixfold coordination with Cl to form a [Sb(1)Cl-5]infinity 1D zigzag chain. Sb(2) atom adopts a fivefold coordination with Cl and is separated from each other by BZA(+) cations. (BZA)(2)SbCl5 crystal shows bright orange-yellow light emission with a photoluminescence quantum yield of 45%. Moreover, the organic-inorganic hybrid metal halide crystals containing antimony have excellent long-term stability, with phase and luminescence keeping nearly unchanged after more than six months in ambient air.

Abstract :

Side reactions and dendrite growth triggered by the unstable interface and inhomogeneous deposition have become the biggest obstacle to the commercialization for lithium metal batteries. In this study, a highly-chlorinated organic-inorganic hybrid interfacial protective layer is developed by rationally tuning the interfacial passivation and robustness to achieve the convenient and efficient Li metal anode. The polyvinyl chloride (PVC) can effectively resist water and oxygen, which is confirmed by density functional theory. The organic-dominant solid electrolyte interphases (SEI) with lithium chloride are investigated by the X-ray photoelectron spectroscopy (XPS) with little mineralization of oxide, such as Li2 O and Li2 CO3 . With such artificial SEI, a uniform and dense lithium deposition morphology are formed and an ultra-long stable cycle of over 500 h are achieved even at an ultra-high current density of 10 mA/cm2 . Moreover, the simple and convenient protected anode also exhibits excellent battery stability when paired with the LiNi0.8 Co0.1 Mn0.1 O2 (NCM811) and LiFePO4 (LFP) cathode, showing great potential for the commercial application of lithium metal batteries.

Abstract&Keyword Cite Version(2)

Abstract :

Improving polarizability is an important strategy for designing high-performance mid-infrared (mid-IR) nonlinear optical (NLO) materials. The substitution of equivalent or aliovalent atoms can manipulate the polarizability by adjusting the symmetry of the polyhedron. Herein, the Li+ and Cd2+ are introduced into the Cu3PS4 as the equivalent and aliovalent dopants for the Cu site. As a result, Li+ can significantly improve the bandgap (E-g) of LixCu3-xPS4 from 2.38 to 2.88 eV, leading to a higher laser-induced damage threshold (LIDT) of 4.9 times than AgGaS2 (AGS) with a comparable second harmonic generation (SHG) response of AGS (26-45 mu m). Interestingly, Cd2+ can improve the SHG response and enlarge the E-g simultaneously. As a result, Cd0.4Cu2.2PS4 has a large SHG response of 10 x AGS at 2050 nm (26-45 mu m) and a LIDT of 2.6 x AGS. Theoretical calculations reveal that lattice vacancies induced by Cd2+ significantly boost polarizability compared to LixCu3-xPS4 with no vacancy, leading to a strong NLO response.

Herein, we synthesize a new serial oxychlorides of La 9 W 6 O 30 Cl (LWOC) and Er 3+ /Yb 3+ , Ho 3+ /Yb 3+ , Tm 3+ /Yb 3+ doped LWOC through molten salt shielding method (MSS) in air, which is more efficient compared to the traditional method in vacuum. The compound of LWOC crystallizes in the tetragonal system space group P 4 2 / nmc (No. 137) with cell parameters a = b = 10.0445 (1) & Aring;, c = 12.6826(4) & Aring;, V = 1279.57(5) & Aring; 3 and Z = 11. The asymmetric unit of LWOC includes three La atoms, one unique W atom, two disordered W atoms with occupancy factors of 0.16(5) and 0.84(5), respectively, one Cl atom and six O atoms. Under the excitation of 980 nm laser, all the Er 3+ /Yb 3+ , Ho 3+ /Yb 3+ and Tm 3+ /Yb 3+ codoped LWOC phosphors have excellent upconversion (UC) luminescence with bright visible light emission. A fluorescence intensity ratio (FIR) type temperature sensor is developed by using LWOC: Er 3+ , Yb 3+ phosphor as sensing media, which has a maximum relative temperature sensitivity ( S r ) of 0.90 % K -1 at 300 K.
