Optimizing and improving the surface activity of Co3O4 sensing materials are crucial for applications in triethylamine detection. Herein, indium-doped Co3O4 hollow microflowers (InCo HMfs), assembled from ultrathin nanosheets, were prepared via a hydrolysis reaction. Three distinct crystal facets─{1 1 0}, {1 1 1}, and {0 0 1}─were observed in 2-InCo HMfs. Results from TEM, XPS, and XAS characterization show that the increase of Co2+ content induced by indium doping promotes the formation of highly active crystal planes in Co3O4. DFT calculations revealed the reasons for the improvement in the gas sensing performance of 2-InCo HMfs and the multiple effects of In ions. Our dual strategy of doping with indium and hydrolysis markedly improved the intrinsic TEA sensing performance of Co3O4, offering a novel avenue for designing high-performance TEA sensors.

Zinc oxide (ZnO) has been widely considered as a promising candidate in electro-chemical devices due to the high electrical transport performance and easy-fabrication. However, the active chemical properties of ZnO nanobelts restrict their application in practical electro-chemical devices. Here, we adopted an indium doping strategy to improve the corrosion resistance of ZnO nanobelts. Compared with other atomic doping methods, the indium doping method not only formed several layers of indium atoms in the body of ZnO nanobelts but also created a ZnxIn1−xO passivated layer on the ZnO nanobelt surface. After doping indium atoms into ZnO nanobelts, the self-corrosion potential increased and the self-corrosion current decreased which greatly reduced its corrosion rate in the electrochemical solution. Furthermore, the electrical transport properties of indium-doped zinc oxide (In–ZnO) nanobelts presented ultrahigh stability even after being soaked in the electrochemical solution for 43 hours. The enhanced anticorrosive quasi-2D ZnO nanobelts offer a promising development of ZnO-based electro-chemical devices.

Recently, there has been significant interest in the utilization of indium-doped cadmium sulfide (CdS) for the detection of chloramphenicol (CAP) in food samples due to its exceptional performance. The objective of this research is to develop a simple, rapid, and highly sensitive sensor for CAP detection. CdS possesses remarkable characteristics as a semiconductor material, including a large specific surface area, abundant pore structure, and excellent electrical conductivity. The electrochemical properties of glassy carbon electrodes (GCE) were comprehensively investigated both in their pristine state and when modified with CdS/GCE, CdIn 2 S 4 /GCE, Cd 1.5 In 2 S 4.5 /GCE, and Cd 2 In 2 S 5 /GCE. The surface areas of the modified electrodes CdIn 2 S 4 /GCE, Cd 1.5 In 2 S 4.5 /GCE, and Cd 2 In 2 S 5 /GCE were measured to be 0.08 cm 2 , 0.097 cm 2 , and 0.25 cm 2 , respectively. Five replicate samples using the optimized proportioned electrode Cd 2 In 2 S 5 /GCE resulted in a response error below 5%. These results indicate that the composite demonstrates exceptional conductivity and reproducibility while maintaining satisfactory sensitivity and high specificity. The proposed sensor based on Cd 2 In 2 S 5 /GCE exhibited an impressive dynamic linear range from 10 nmol/L to 20 μmol/L with an exceptionally low detection limit of 3.8 nmol/L and remarkable sensitivity of 0.38 μA μm −1 cm −2 . This sensor successfully quantified CAP in water samples with a satisfactory recovery rate ranging from 99.5% to 100.3%, accompanied by an RSD below 7.6%. Consequently,this developed electrochemical sensor presents itself as the optimal choice for simultaneous determination of CAP in both food and water samples.

In this study, In-doped SnS 2 nanostructures were synthesized by a one-step hydrothermal method. Characterization results demonstrated that S vacancies were successfully constructed in the synthesized material. Samples doped with different masses of indium were prepared. Among them, the In/V s2 -SnS 2 sample with moderate sulfur vacancy content the In/V s2 -SnS 2 showed the best ammonia detection response (500 ppm) at room temperature, and the peak response reached 2392. Moreover, the sensor exhibited a response/recovery time of 37.5s/3.3s. The adsorption energies of ammonia on the pure phase SnS 2 surface and S vacancies were determined by the first principle DFT calculations. The theoretical analysis agreed well with the experimental results, suggesting that the S vacancies provided more active sites for effective adsorption, favoring the sensitive detection of ammonia molecules. The proposed study demonstrates that In-doping created S vacancies in SnS 2 , which is promising for gas sensitization, laying the foundation for high-performance room-temperature gas sensors.

Improving photocatalytic activity is crucial for promoting photocatalytic hydrogen production. Element doping is a feasible strategy to accelerate carrier separation and migration rate. Herein, a simple one-pot hydrothermal process was used to create In doped Sn 3 O 4 composite photocatalyst. It was demonstrated that the addition of In considerably raises the concentration of oxygen vacancy , which provides more unsaturated active sites, thus regulating the photocatalyst's electronic structure and surface properties, and promoting the carrier migration efficiency. Meanwhile, the light absorption range of samples after doping is redshifted, and the light absorption capacity is enhanced, which effectively improves the photocatalytic activity. Due to this, the optimal sample's average hydrogen production under visible light reached 22.83 μmol g −1 h −1 , 4.5 folds more than that of Sn 3 O 4 , and shown good stability. This research presents a novel approach for the development of metal oxide photocatalyst with excellent activity and durability.

The perovskite scintillators have been extensively studied recently for their merits of tunable emission spectra and simple preparation processes. However, the practical applications of perovskite scintillator-based X-ray image sensor are still impeded by inadequate radioluminescence, poor environmental stability, and low imaging resolution. Herein, we demonstrate a scalable co-firing method to fabricate high-quality lead-free Cs 3 Cu 2 I 5 perovskite scintillator and an Indium (In)-doping strategy is introduced to enhance its radioluminescence performance at the same time. The In-doped Cs 3 Cu 2 I 5 obtains a high PLQY of 77.9% and a relative light output of 53372 ph/MeV, which are 0.34 and 1.08 times higher than those of the undoped counterpart, respectively. The X-ray detection limit of the In:Cs 3 Cu 2 I 5 can reach 150.55 nGy air /s, 36.53 times lower than the requirement for X-ray medical diagnosis. The synthesized scintillator also shows superior stability under continuous high dose X-ray irradiation of 6800 μGy air /s for 120 minutes, maintaining 95% of its initial radioluminescence intensity. Furthermore, a large-area (300 cm 2 ) flexible perovskite scintillator film is prepared, which owns a much competitive resolution of 10 lp/mm and less distortion in X-ray imaging. This work provides a practical path for the wide application of perovskite scintillator in the field of X-ray detection and imaging in near future.

Configurational entropy composites of In-doped Zn(O,S)/Zn-doped In(OH) 3-x S x has been synthesized with a one-step hydrothermal method and carefully characterized with XRD , XPS , SEM, TEM, DRS , PL , EIS , TPC , CV , and MS analyses. The composites were prepared with different sulfur amounts to obtain the optimum performance of visible-light photocatalytic HER . The primary phases of ZnS and In(OH) 3 were formed after the hydrothermal process. However, the results indicated In and O were doped into ZnS lattice and induced lower bandgap values (~2.71–2.84 eV) which are active in visible-light illumination. Simultaneously, the excess Zn and S were also doped to In(OH) 3 with lower bandgap values (~3.38–4.63 eV). The variation of bandgap values is due to the hybridization of In 5s5p to Zn 4s4p and O 2p to S 3p orbitals. As a result, In-doped Zn(O,S) and Zn-doped In(OH) 3-x S x will be a visible-light active material for photoreaction and a favorable phase for electron transfer , respectively. Furthermore, it is also related to a possible antisite-defect formation with I n Z n + to help the electron trapping and enhance the photocarrier separation, leading to an efficient photocatalytic activity . ZI-S1 with additional 5-mmol thioacetamide was found as the catalyst with the highest HER performance which achieved 730 μmol/g·h under visible-light illumination. A plausible photocatalytic HER mechanism is discussed and proposed in this work.

So far, for photoelectric metal oxide semiconductor gas sensors, it is a huge bottleneck to achieve high response performance and low detection limit of formaldehyde at room temperature. This work introduced the synthesis of cauliflower-like graphene-modified In-doped ZnO (GR/In-ZnO) composites via a facile one-pot method with a large comparative surface area for low-concentration formaldehyde sensing at room temperature. GR/In-ZnO-300 showed the highest response to 10 ppm formaldehyde, up to 1891%, which was 12 times that of In-ZnO-300. In addition, the theoretical detection limit of GR/In-ZnO-300 was as low as 13 ppb, and the response at this concentration was 137%. Through the characterization of Surface Photovoltage (SPV), Transient Photovoltage (TPV), Surface Photocurrent (SPC), X-ray Photoelectron Spectroscopy (XPS), and nitrogen gas adsorption isotherms , good formaldehyde sensing performance of GR/In-ZnO-300 was attributed to the excellent separation and transmission capacity of photogenerated carriers, the high specific surface area (109.2 m 2 /g), and abundant oxygen defects on the surface. This work provides a feasible strategy for the design of low-concentration formaldehyde sensing materials with a rapid response at room temperature.

Two dimensional (2D) tin disulfide (SnS2) has attracted growing interest as a promising high performance photodetector with superior performance such as fast response time, high responsivity, and good stability. However, SnS2-based photodetectors still face great challenges, and the photodetection performance needs to be improved for practical applications. Herein, indium-doped SnS2 (In-SnS2) few layers were exfoliated from CVT-grown single crystals, which were synthesized by chemical vapor transport. Photodetectors based on In-SnS2 few layers were fabricated and detected. Compared with photodetectors based on pristine SnS2, photodetectors based on In-SnS2 few layers exhibited better photodetection performances, including higher responsivities, higher external quantum efficiencies, and greater normalized detectivities. The responsivity (R), external quantum efficiency (EQE), and normalized detectivity (D*) were increased by up to 2 orders of magnitude after In doping. Considering responsivity and response time, the photodetector based on 1.4 at. % In-SnS2 few layers exhibited an optimal photodetection performance with a high R of 153.8 A/W, a high EQE of 4.72 × 104 %, a great D* of 5.81 × 1012 Jones, and a short response time of 13 ms. Our work provides an efficient path to enhance photodetection performances of photodetectors based on SnS2 for future high-performance optoelectronic applications.

Scintillators are widely utilized in high-energy radiation detection in view of their high light yield and short fluorescence decay time. However, constrained by their current shortcomings, such as complex fabrication procedures, high temperature, and difficulty in the large scale, it is difficult to meet the increasing demand for cost-effective, flexible, and environment-friendly X-ray detection using traditional scintillators. Perovskite-related cesium copper halide scintillators have recently received multitudinous research due to their tunable emission wavelength, high photoluminescence quantum yield (PLQY), and excellent optical properties. Herein, we demonstrated a facile solution-synthesis route for indium-doped all-inorganic cesium copper iodide (Cs3Cu2I5) powders and a high scintillation yield flexible film utilizing indium-doped Cs3Cu2I5 powders. The large area flexible films achieved a PLQY as high as 90.2% by appropriately adjusting the indium doping concentration, much higher than the undoped one (73.9%). Moreover, benefiting from low self-absorption and high PLQY, the Cs3Cu2I5:In films exhibited ultralow detection limit of 56.2 nGy/s, high spatial resolution up to 11.3 lp/mm, and marvelous relative light output with strong stability, facilitating that Cs3Cu2I5:In films are excellent candidates for X-ray medical radiography. Our work provides an effective strategy for developing environment-friendly, low-cost, and efficient scintillator films, showing great potential in the application of high-performance X-ray imaging.

White light-emitting diodes (WLEDs) are the key components in the next-generation lighting and display devices. The inherent toxicity of Cd/Pb-based quantum dots (QDs) limits the further application in WLEDs. Recently, more attention is focused on eco-friendly QDs and their WLEDs, especially the phosphor-free WLEDs based on mono-component, which profits from bias-insensitive color stability. However, the imbalanced carrier distribution between red-green-blue luminescent centers, even the absence of a certain luminescent center, hinders their balanced and stable photoluminescence/electroluminescence (PL/EL). Here, an In 3+ -doped strategy in Zn-Cu-Ga-S@ZnS QDs is first proposed, and the balanced carrier distribution is realized by non-equivalent substitution and In 3+ doping concentration modulation. The alleviation of the green emitter by the In 3+ -related red emitter and the compensation of blue emitter by the Zn-related electronic states contribute to the balanced red-green-blue emitting with high PL quantum yield (PLQY) of 95.3% and long lifetime (T 90 ) of over 1100 h in atmospheric conditions. Thus, the In 3+ -doped WLEDs can achieve exceedingly slight proportional variations between red-green-blue EL intensity over time (∆CIE = (0.007, 0.009)), and high champion CRI of 94.9. This study proposes a single-component QD with balanced and stable red-green-blue PL/EL spectrum, meeting the requirements of lighting and display.

In-substituted YIG ferrite (Y 3 Fe 5 − x In x O 12 ) materials were prepared by citrate nitrate sol–gel method. Phase formation, microstructure, and magnetic properties were investigated, and the effects of In-substitution were discussed detailed. X-ray diffraction results showed the In-substitution did not change the phase formation of YIG ferrite, but cause the lattice constants change slowly. Scanning electron microscopy showed the materials prepared by sol-gel method had small gain size, and In 3+ enhanced grain growth. The high-substituted content had pores among grain boundaries, which was an influence factor on magnetic property. With In-substituted increase, saturation magnetization ( σ ) increased from 21.77emu/g ( x = 0.0) to 26.94 emu/g (4π M S =1639.2 Gs) when x = 0.4, and then decreased to 20.27 emu/g (4π M S =1230.0 Gs, x = 0.5). Meanwhile, the coercivity ( H C ) decreased from 12.3 Oe to 12.1 Oe ( x = 0.3) and then increased to 13.6 Oe ( x = 0.5). For ferromagnetic resonance (FMR) linewidth (Δ H ), the narrow FMR value was Δ H = 62.82 Oe at x = 0.4. The anisotropy linewidth Δ H a and porosity linewidth Δ H p were mainly influence factors on linewidth of materials, and the magnetism was discussed detailed. The narrow FMR linewidth and high saturation magnetization suggested the possible use of these materials in high-frequency microwave applications.
