Nanoscaled SnO 2 with different morphologies has been synthesized via a simple hydrothermal process at 180 °C using polyvinylpyrrolidone (PVP), sodium dodecyl sulfonate (SDS), cetyl trimethyl ammonium bromide (CTAB) or tetrapropyl ammonium bromide (TPAB) as surfactant . All the prepared SnO 2 are of a tetragonal crystal structure. Nanocubes, nanorods , nanosheets , nanobelts and nanoparticles were prepared when changing the type and dosage of organic surfactants. It is shown that anionic surfactant (SDS) and cationic surfactant (CTAB or TPAB) at their suitable addition amounts can largely influence the morphologies of SnO 2 nanocrystals . The effect is significantly dependent on the solvent types: water or ethanol. The non-ionic surfactant (PVP) can also change the morphologies like SDS but the impacts are less obvious. The effect of surfactants on the shape and size of SnO 2 nanoparticles was discussed in detail. The particle growth mechanism is described based on the electrostatic interactions and Van der Waals’ forces.

Colloidal platinum–ruthenium bimetallic nanoparticles with 2.3 nm were synthesized in solution and then immobilized on tin dioxide powder to make a supported nanocatalyst (Pt–Ru/SnO 2 ). The immobilized bimetallic nanoparticles had the same size and size distribution as the solution dispersed ones. Selective hydrogenation of o -chloronitrobenzene to o -chloroaniline was performed over the as-prepared Pt–Ru/SnO 2 nanocatalyst without using any solvent; 99.5% selectivity to o -chloroaniline at ∼100% conversion was achieved.

The rapid development of artificial intelligent and internet of things calls for high-performance multifunctional devices for synchronous detection of a wide variety of environmental signals, such as gas, light, and humidity. Herein, highly crystallized tin dioxide (SnO 2 ) microwires (MWs) with low density of point defects are synthesized by the chemical vapor deposition method and constructed into a multifunctional device for photo and humidity sensing. The device shows excellent photoelectric performances, for example, ultralow dark current of ≈10 −13 A, ultrahigh on–off ratio of >10 7 , UV/visible rejection ratio of R 300 nm / R 400 nm > 10 7 , specific detectivity ( D *) of 1.16 × 10 15 Jones, linear dynamic range (LDR) of 152 dB, high responsivity of 18 A W −1 , and fast photoresponse speed of t rise / t decay = 2.7 µs/2.5 ms at 5 V bias. Furthermore, the p-CuI/n-SnO 2 heterojunction shows outstanding self-powered properties, such as responsivity of 8.98 mA W −1 , specific detectivity of 1.98 × 10 12 Jones and LDR of 106 dB at 0 V bias. Additionally, the SnO 2 MWs also show high sensitivity to ambient humidity changes. Therefore, the SnO 2 MWs show high potential for multifunctional applications, such as UV photodetector and humidity sensor.

We report a simple and low-cost approach to enhance the longstanding stability of the perovskite solar cell (PSC) through the application of low-temperature grown SnO 2 nanorod (NR) arrays. SnO 2 NR arrays were fabricated by an aqueous synthesis method in the presence of hydrochloric acid and using thin compact SnO 2 as seeds. The influence of HCl concentration on the photovoltaic (PV) performance of the SnO 2 NR array based PSC device was investigated. The formed crystalline SnO 2 nanorods with square transversal-sections were oriented on the FTO facets in a well-defined and perpendicular fashion at an optimal HCl concentration. The optimized width and length for SnO 2 nanorods were 30 nm and 150 nm, respectively. Consequently, efficient and stable SnO 2 nanorod based perovskite devices were obtained with an average power conversion efficiency (PCE) of 16.57%. The SnO 2 nanorod array based PSCs demonstrated considerably better ultraviolet (UV) and ambient air stability than the planar SnO 2 and notably mesoporous TiO 2 solar cells. This paper provides a prospective scheme to grow high-quality three-dimensional SnO 2 nanorod arrays for highly stable and efficient PSCs.

Interfacial modification as a feasible strategy to improve the properties of perovskite solar cells (PSCs) has been widely studied in recent years. In this work, PbCl 2 modification at the interface of SnO 2 /CH 3 NH 3 PbI 3 was used for CH 3 NH 3 PbI 3 -based planar PSCs. The introduction of PbCl 2 between SnO 2 and CH 3 NH 3 PbI 3 layers boosted the crystallization of perovskite film, which promoted the photovoltaic properties of corresponding PSCs. The open circuit voltage ( V OC ) and fill factor (FF) of the PbCl 2 -modified devices (1 mg/mL) were 1.11 V and 0.79, respectively, which were both higher than those of the reference devices without PbCl 2 (1.04 V and 0.76). Moreover, a steady-state power output efficiency exceeding 19% was obtained for the PbCl 2 -modified devices (1 mg/mL), which implied that PbCl 2 modification was an effective and low cost strategy for efficient PSCs.

Graphite nanosheets coated by LiF/SnO 2 composites are designed to obtain a lithium ion anode material with excellent performance. LiF nanoparticles play a significant role in improving the electrochemical performance by inhibiting electrolyte decomposition and providing excess Li sources during cycling. The obtained LiF@SnO 2 @C electrode shows an outstanding capacity of 951.9 mAhg −1 at 0.2 Ag -1 after 370 cycles and excellent long cycling performance of 650.0 mAhg −1 at 1.0 Ag -1 after 930 cycles. First-principles calculations demonstrate that F-doped SnO 2 (−2211.8 eV) has a lower free energy compared to SnO 2 (−1937.4 eV), resulting in a robust composite architecture that gives rise to high cycling stability.

Well-crystallized one-dimensional (1D) SnO 2 nanobelts were in situ prepared using a simple water-assisted chemical vapor deposition (CVD) method. The small Sn particles with Au-modifications were used as source materials instead of big size Sn grains to ensure the high yield of SnO 2 belts. The Au layer was modified on the small Sn particles by treating Sn powders in HAuCl 4 solution combined with the UV irradiation. The as-prepared SnO 2 nanobelts were characterized by SEM, HRTEM, XRD, EDS and XPS. These results indicate that the growth temperature plays an important role in controlling the length-to-width ratio of nanobelts. The length-to-width ratio decreases with the growth temperature from 850 °C to 1000 °C. The nanobelts prepared at 850 °C shows a single-crystalline tetragonal rutile phase with a high length-to-width ratio (approximately tens of microns in length and 40–70 nm in width). However, below 850 °C, nanobelts cannot be formed. The as-prepared nanobelts exhibited excellent sensing properties compared with SnO 2 nanoparticles and high sensing selectivity towards NO 2 . The high sensing selectivity to NO 2 is attributed to the oxygen vacancies presenting in the as-prepared nanobelts.

Trivalent iron (Fe 3+ ) has attracted extensive attention as an environmentally friendly and cost-effective near-infrared (NIR) emitting activator ion. However, its weak absorption in the blue-violet light region and relatively low internal quantum efficiency (IQE) have long constrained its practical applications. In this study, a series of Ca 3 Ga 2-x Sn 2 GeO 12 : xFe 3+ NIR phosphors with a cubic garnet structure was successfully synthesized via a high-temperature solid-state reaction method. Efficient NIR luminescence under long-wave ultraviolet (LWUV) chip excitation was observed, exhibiting broadband NIR emission centered at 740 nm. Remarkably, the phosphor achieves an internal quantum efficiency (IQE) as high as 82.3%, representing the highest efficiency reported to date for Fe 3+ -doped NIR phosphors under blue-violet light excitation. Temperature-dependent luminescence analysis reveals excellent thermal stability: the integrated emission intensity at 423 K retains 67.06% of its initial value at room temperature. A prototype NIR phosphor-converted LED (pc-LED) device fabricated with the studied phosphor and a commercial chip (400–410 nm) exhibits stable electroluminescence performance and good output power conversion. In summary, the Ca 3 Ga 2-x Sn 2 GeO 12 : xFe 3+ phosphor, with its efficient luminescence under blue-violet light excitation, outstanding thermal stability, and temperature-independent emission peak position, demonstrates significant application potential in the field of high-efficiency and high-stability NIR light sources.

BaTiO 3 -based piezoelectric ceramics have emerged as highly promising candidates for various applications, due to their excellent piezoelectricity. In this work, the [001] C textured Ba 0.97 Ca 0.03 Ti 0.96 Sn 0.04 O 3 piezoelectric ceramics were synthesized using the templated grain growth (TGG) method with the assistance of ZnO and Li 2 O. The effects of ZnO and Li 2 O on microstructure evolution, phase structure, texture development and piezoelectric properties were investigated systematically. Both ZnO and Li 2 O exhibit a pronounced promoting effect on oriented BCTS grain growth, enabling the achievement of a high texture degree F 001 of 98% at a relatively low sintering temperature of 1325 °C. The highly textured BCTS ceramics with Li 2 O exhibit to a substantial enhancement in piezoelectric performance: maximum strain S m , the piezoelectric coefficient d 33 and the figure of merit d 33 · g 33 reach 0.25%, 576 pC/N and 28.7 × 10⁻¹ ² m²/N, respectively. The highly preferred [001] C orientation, coexistence of O + T phases, and optimized ferroelectric domain structure synergistically contribute to the significant piezoelectric property enhancement. These results demonstrate the great potential of environmentally friendly textured BCTS-based ceramics for applications in piezo-sensors and energy harvesters.

SrTiO 3 (ST) ceramics exhibit high breakdown strength ( E b ) but suffer from low polarization, limiting their recoverable energy density ( W rec ). Herein, we propose a multivalent Sn dual-site doping strategy to concurrently enhance polarization and E b . The co-occupation of A-sites by Sn 2 + and B-sites by Sn 4+ promotes the formation of polar nanoregions (PNRs) while suppressing deleterious interfacial polarization. This synergistic mechanism yields a substantial maximum polarization of 25 μC/cm 2 and a robust E b of 640 kV/cm in the optimal composition ( x = 0.02). Consequently, a superior W rec of 6.1 J/cm 3 and a high efficiency ( η ) of 90.58% are achieved. Furthermore, the ceramics demonstrate outstanding pulsed charge-discharge performance, delivering a power density of 125 MW/cm 3 with an ultrafast discharge time of 23.3 ns. This work highlights the critical role of defect engineering and valence state engineering in optimizing the energy storage properties of ST-based ceramics.

Fabricating high-performance high-entropy ceramics (HECs) with complex geometries remains a challenge. Here, high-entropy fluorite (Ce 0.2 Zr 0.2 Ti 0.2 Sn 0.2 Ca 0.2 )O 2-δ ceramics were fabricated by digital light processing (DLP). The effects of slurry solid loading (76–80 wt%) on sintering behavior, microstructure, mechanical properties, and thermal transport were systematically investigated and compared with pressureless sintering. Increasing the solid loading to 80 wt% increased the green-body density, reduced linear shrinkage, and produced ceramics with a bulk density exceeding 5.0 g/cm³ (>88% theoretical density). EDS analyses revealed compositionally homogeneous microstructures without detectable micron-scale elemental segregation within the spatial resolution of the present measurements. DLP-80 HEFO exhibited the highest flexural and compressive strengths among the printed samples while maintaining low thermal conductivity values of 1.7–2.2 W·m⁻¹ ·K⁻¹ from 25 to 1000 °C. This work demonstrates that optimizing slurry solid loading provides an effective strategy for fabricating high-entropy fluorite ceramics with balanced densification, mechanical performance, and thermal-insulation capability.

en This link goes to a English section zh This link goes to a Chinese section The development of high-performance photodetectors critically relies on innovative interfacial band engineering, a strategy that enables the synergistic enhancement of photocurrent and drastic suppression of dark current. Herein, a self-powered ultraviolet (UV) photodetector is demonstrated based on a NiO/La-doped SrSnO 3 (LSSO)/Nb-doped SrTiO 3 (NSTO) dual heterojunction. Benefiting from the reinforced interfacial potential barriers and multiple built-in electric fields at both the NiO/LSSO and LSSO/NSTO interfaces, the device achieves highly efficient charge separation while effectively inhibiting carrier leakage in the dark. Consequently, the photodetector exhibits an ultra-low dark current of 0.18 pA at zero bias. Under 254 nm UV illumination, the device delivers a high responsivity of 41.81 mA W −1 , a specific detectivity of 7.87 × 10 12 Jones, a photocurrent-to-dark-current ratio as high as 4.4 × 10 4 , and rapid response times (rise/fall) of 2.89/13.93 ms. These results underscore the advantages of the dual-heterojunction architecture in boosting photoelectric conversion efficiency and suppressing noise, thereby providing a robust strategy for high-performance, oxide-based self-powered UV photodetection. 摘要 en This link goes to a English section zh This link goes to a Chinese section 高性能光电探测器的研发关键在于创新性的界面能带工程,该策略能够协同增强光生电流并显著抑制暗电流。本文报道了一种基于NiO/La:SrSnO 3 (LSSO)/Nb:SrTiO 3 (NSTO)双异质结结构的自供电紫外光电探测器。得益于NiO/LSSO和LSSO/NSTO界面处增强的界面势垒和多重内置电场,该器件在有效抑制暗态下载流子泄漏的同时,实现了高效的电荷分离。结果表明,该探测器在零偏压下表现出0.18 pA的极低暗电流。在254 nm紫外光照射下,器件的响应度达到41.81 mA W −1 、探测率为7.87 × 10 12 Jones,光暗电流比高达4.4 × 10 4 ,并具备2.89/13.93 ms (上升/下降时间)的快速响应特性。上述结果充分表明,双异质结结构在提升光电转换效率和抑制噪声方面具有显著优势,为构建高性能氧化物自供能紫外光电探测器提供了一种有效的设计策略。
