Garnet type Li 7 La 3 Zr 2 O 12 solid electrolyte exhibits excellent thermal stability and high ionic conductivity, which is an ideal solid electrolyte. However, it is found that the cubic phase is a high conductivity phase and the synthesis condition is harsh. Therefore, low temperature synthesis and partial element substitution are expected to prepare cubic phase LLZO. In this paper, the LLZO cubic phase structure is stabilized by electrospinning technology and high-priced cation substitution strategy, and the transportation efficiency of lithium ions is improved. The experimental results show that LLZO NFs inorganic filler with stable cubic phase structure is obtained when the molar amount of In 3+ is 0.2. The In 3+ with large ion radius replaces the Li + inside the crystal, effectively increases the lithium vacancy concentration, and increases the Li + transport path inside the crystal, and successfully doubles the ionic conductivity of the composite solid electrolyte at 60 °C (9.39 × 10 −4 S/cm). The lithium ions migration number and electrochemical window were increased to 0.19 and 5.2 V respectively. With excellent cycle performance (60 °C), it can cycle 2000 cycles at a high rate of 0.5 C charge and discharge, and the Coulomb efficiency has been close to 100 %. Li|PL-LILZO NFs (0.2)|LFP all-solid-state lithium batteries can light small bulbs at room temperature and have practical application prospects. Therefore, in the composite electrolyte, the increase of the lithium ions pathway inside the active inorganic filler crystal will also improve the comprehensive performance of the composite electrolyte for preparation.

Cu–In–S ternary nanocrystals (NCs), with an average size of less than 10 nm, were synthesized in an aqueous solution containing bovine serum albumin (BSA). X-Ray powder diffraction (XRD) and selected-area electron diffraction (SAED) analyses showed that these NCs featured a roquesite structure. The composition of the NCs could be adjusted by controlling the molar ratio of the starting Cu/In precursors in the reaction solution, which led to a tunable band gap ranging from 1.48 eV to 2.30 eV. Cytotoxicity testing showed that the BSA-stabilized Cu–In–S NCs had little effect on the cell viability, which suggested that they are user-friendly and environmentally benign. With low cost, minimal energy input and environmental impact, this simple approach shows great potential for industrial applications.

The In 2.77 S 4 microspheres had been firstly fabricated by using polyethylene glycol (PEG) as the morphological modifier and then used to hybridize with In(OH) 3 nanocubes by a simply depositional method. The structure, optical properties, morphology, chemical compositions, and charge carrier behaviors of the as-prepared In 2.77 S 4 /In(OH) 3 composites were characterized, respectively. The methyl orange, tetracycline, rhodamine B, and Cr(VI) dilute solution were selected to evaluate their photocatalytic activities. Experimental results showed that In(OH) 3 nanocubes could improve the photocatalytic activity and recyclability of the In 2.77 S 4 microspheres under the visible light irradiation. With the usage of In(OH) 3 increased, the photocatalytic efficiency of the hybrids was firstly increased and then decreased. When the mass ratios of In 2.77 S 4 to In(OH) 3 were 6:2, it reached the maximum of 100% in 15 min for methyl orange, obviously higher than 67.4% of In 2.77 S 4 and 1.1% of In(OH) 3 . Meanwhile, it could also oxidize 85.6% of tetracycline in 20 min, 97.8% of rhodamine B in 7.5 min, and reduce 92.9% of Cr(VI) in 30 min under the visible light irradiation. Moreover, it could still degrade 91.7% of methyl orange solution after 3 cycles, which was much higher than 40.7% of In 2.77 S 4 microspheres. In addition, the possible mechanism of enhancing photocatalytic properties was proposed.

Element doping is an excellent strategy to promote charge separation and reaction kinetics of photocatalyst, which plays significant role in accelerating the sustainable energy development process. Herein, Ni, In co-doped ZnIn 2 S 4 photocatalyst was prepared by a microwave-assisted solvothermal method. The rapid crystallization of ZnIn 2 S 4 resulted in partial In atoms substituted Zn atom during the formation of [ZnS] 4 layer. In doping in tetrahedral Zn sites increases the electron delocalization around In sites, hence reduces the electronic potential wells along Z axis. Ni doping in tetrahedral Zn sites decreases the negative charge on the S sits, which balances the H adsorption/desorption, further boosting the photocatalytic activity. As a result, Ni, In co-doped ZnIn 2 S 4 possess an optimal photocatalytic H 2 evolution property of 21.94 μmol·h −1 , which is nearly 1.8 and 6.1 times of In-ZnIn 2 S 4 (11.78 μmol·h −1 ) and ZnIn 2 S 4 (3.6 μmol·h −1 ).

Cellulose-based bioplastics with degradability and remarkable mechanical performance have recently attracted increasing attention. As a high-performance material, cellulose-based bioplastics have a strong potential to replace synthetic plastic substrates in many applications. However, its poor shielding performance to UV light limit its application. In this work, transparent and UV-blocking MIL-68(In)-NH 2 @cellulose bioplastic (M(In)CBP) sheets are fabricated via a featured processing method, i.e., cellulose liquefaction, rapid solidification, in-situ synthesis and hot-press drying. The as-obtained functional bioplastic sheet (M(In)CBP1) exhibits high visible-light transparence (74.7% a 600 nm) and the existence of MIL-68(In)-NH 2 allows superior UV-blocking ability (below 400 nm, transmittance was under 4%). The M(In)CBP sheets show high photostability even after continuous UV irradiation (365 nm) for over 12 h. The superior UV-shielding performance is attributed to the uniform distribution and the high UV absorbance of MIL-68(In)-NH 2 in M(In)CBP sheets. High resistance to penetration by aqueous/nonaqueous liquids was proved. Moreover, the M(In)CBP sheets also show excellent mechanical properties and thermal stability. The present work designed a UV-blocking bioplastic constructed from cellulose and MIL-68(In)-NH 2 , which is potential candidates to replace synthetic plastics in many advanced applications such as a UV protection layer for electronic products, or useful as packaging materials to prevent food spoilage.

Ratio fluorescence has attracted much attention because of its self-calibration properties. However, it is difficult to obtain suitable fluorescent materials with well-resolved signals simultaneously under one excitation. In this work, we report a different strategy, using MIL-68(In)-NH 2 as both the fluorescence element and the scattered light unit, and coupling the fluorescence and the scattered light to construct the fluorescence and scattered light ratio system. Based on the optical properties and the second-order scattering (SOS) of the material nanoparticles , the synthesized MIL-68(In)-NH 2 can be used to realize the ratio detection of Hg 2+ . Because the scattering intensity of small particle MIL-68(In)-NH 2 is weak, SOS is not obvious. When Hg 2+ is introduced the coordination reaction between the amino nitrogen atoms of MIL-68(In)-NH 2 and Hg 2+ make the particles larger, resulting in the decrease of fluorescence and the enhancement of SOS. As a result, a novel Hg 2+ ratiometric detection method is developed by using the dual signal responses of the fluorescence and scattering. Under the optimal conditions (pH = 6, reaction time 5 min, room temperature , and the maximum excitation wavelength 365 nm), the linear range of the method is 0–100 μM, and the detection limit is 5.8 nM (Ksv = 9.89 × 10 9 M −1 ). In addition, the probe is successfully used to evaluate Hg 2+ in actual water samples. Compared with the traditional method of recording only the fluorescence signal, the proposed fluorescence-scattering method provides a new strategy for the design of ratiometric sensors.

This work describes a facile approach for the delaminating of Ni–In-layered double hydroxides (LDHs) by the intercalation of acetate anions in the LDHs gallery using co-precipitation method. The acetate-intercalated Ni–In LDHs exhibited swelling behavior in water and delaminated into semitransparent suspensions on the action of water. The transmission electron microscopy (TEM) and atomic force microscopic (AFM) observations revealed the formation of unilamellar LDHs nanosheets. This simple method did not need reflux at high temperatures, overcoming the deficiency of using organic solvents, resulting in a steady colloidal suspension of 2D nanosheets. The unique properties of 2D ultrathin nanosheets with full access to the positively charged activity sites make them attractive in terms of the improvement of DNA adsorption. The effect of dosage on the adsorption of DNA and the adsorption isotherm were investigated in detail. The equilibrium data were found to be well described by both the Langmuir and Freundlich models. Based on the mechanism of adsorption, the adsorption sites of exfoliated nanosheets can be easily occupied by highly negatively charged small anions through electrostatic interactions. The adsorbed DNA can be released via the addition of a hydrogen phosphate solution.

In the present work, we reported the synthesis of Mn2+-doped Zn–In–S quantum dots (QDs) with high optical performance in a controlled manner. The effects of the temperature, the introduced ODE-S amount and Zn/In ratios in the raw materials, as well as the Mn2+ doping concentrations on the photoluminescence (PL) properties of Mn2+-doped Zn–In–S QDs were investigated systematically. The resultant QDs exhibit tunable bandgaps ranging from 2.9 to 3.7 eV, well-resolved Mn2+ d–d emission with a PL quantum yield (QY) of 56% and a surprisingly long excited state lifetime up to ∼4.2 ms, suggesting their excellent PL properties. Meanwhile, the initial high PL QY of the obtained Mn2+-doped Zn–In–S QDs in organic solvents could be preserved very well once they were transferred into aqueous media via ligand exchange. Furthermore, the as-synthesized QDs exhibit excellent thermal stability up to 200 °C in a crude solution.

Currently, the performance of quantum-dot light-emitting diodes (QLEDs) based on environmental-friendly Cu─In─Zn─S quantum dots (QDs) still lags far behind that of Cd-QDs-based devices. Here it is demonstrated that the unique trap-related recombination in Cu─In─Zn─S QDs is mainly responsible for the low device efficiency. The luminous efficiency of Cu─In─Zn─S-based QLEDs is rather sensitive to the temperature and hole-transporting layers (HTLs) due to the susceptible thermal-related trappingdetrapping processes of holes in radiative Cu-related traps. The holes in Cu-related traps can be quenched by escaping to the valence band of the QDs or/and transferring to the adjacent HTLs. An HTL with low highest occupied molecular orbitals is desired to enhance the hole injection and hinder the aforementioned hole transfer. As a result, a high device efficiency of 6.0 cd A −1 is achieved at room temperature, which is attributed to suppressed HTL-induced emission quenching and efficient valence-band-dominated hole injection from HTL to the QDs. The device efficiency is further increased to 13.2 cd A −1 at 150K by suppressing thermal-induced quenching.

In this article, a new simple one-step process to fabricate Cd–In–S luminescent quantum dot thin films (QDTFs) is provided. Metal sulfide precursor solutions were manufactured by directly adding a certain amount of butylamine and carbon disulfide in the ethanol solution followed by dissolving Cd(OH)2 and In(OH)3 powder. Cd–In–S luminescent QDTFs can be obtained by mixing Cd and In precursor solutions and then spinning on a cover slip and annealing on a hot plate at 190 °C under air atmosphere directly without complicated synthesis method. By changing the sintering parameters including the temperature, time and ratios of (Cd+In)/ligand, the Cd–In–S luminescent QDTFs covering the entire visible light wavelength from 470 to 628 nm can be obtained. The Cd–In–S luminescent QDTFs exhibited remarkable optical properties and has potential application in solar cell and light emitting diode, with the photoluminescence quantum yield of up to 36.5%.

Synthesis of nontoxic quantum dots (QDs) with excellent optical properties in aqueous phase to replace organic dyes with photobleaching drawbacks used in bioimaging has become a research priority. Herein, water-soluble Ag-In-Zn-S (AIZS) QDs were prepared by microwave-assisted hydrothermal method at 110 °C for 40 min. The luminescence peak of AIZS QDs was varied from 684.5 nm to 576.2 nm when the Ag/In molar ratio was changed in the range of 1/2–1/10. A clear blue-shift of PL peak from 616.8 nm to 551.5 nm was observed with increasing Zn 2+ element with the Ag/Zn molar ratio in the range of 1/0–1/14, indicating that the increase of Zn 2+ content caused the increase of band gap. The AIZS QDs exhibit the highest photoluminescent quantum yield (PLQY) of 20.67 % with the molar ratio of Ag/In/Zn=1/6/2, and fluorescence lifetime upped to 294.69 ns. Finally, human hepatocellular carcinomas (HepG2) cells and Hela cells were incubated with AIZS QDs solution at different concentrations and were found to have a high survival rate. Furthermore, HepG2 cells emitted bright yellow light when stimulated upon UV excitation, indicating that AIZS QDs can be applied in bioimaging field.

Functionalization has emerged as a pivotal endeavor to tailor the surface properties of photocatalysts. We propose a facile amine functionalization strategy to establish a Cu−In−Zn−S (CIZS)/NiS x hybrid with covalent bonds using individual ethylenediamine (EDA) molecules. Our approach witnesses a remarkable photocatalytic hydrogen evolution (PHE) competence of 65.93 mmol g −1 h −1 driven by visible light, the highest value yielded by CIZS to date. X-ray absorption spectra of CIZS and density functional theory (DFT) calculations confirm the crucial amine N→Cu coordination after amine functionalization. The new emerging coordination via lone-pair electron donation profitably accesses the regulation of the coordination environment, electronic structures, and carrier behavior. Moreover, individual EDA molecule with two-terminal −NH 2 group serves as a molecular bridge to hybrid CIZS and NiS x cocatalyst via N→Cu and N→Ni coordination, favorably promoting efficient charge transport. This study provides advances in practical functionalizing photocatalysts.
