A novel CaIn2S4 with three-dimensional octahedral nano-blocks (ONBs) are successfully synthesized on fluorine-doped tin oxide (FTO) substrate by a simple hydrothermal method. The CaIn2S4 ONBs are uniform grown and scattered on the whole FTO substrate with high regular and symmetric morphology as well as average diagonal length of about 600 nm. Based on the as-synthesized CaIn2S4 ONBs, a photodetector (PD) is fabricated. Satisfyingly, it is found that the CaIn2S4 ONBs PD achieves a broad-band response ranging from ultraviolet (UV) to visible ( vis) light at zero bias voltage. It is also significant that the CaIn2S4 ONBs PD enables a fast response, in which the rise time and decay time are less than 0.15 and 0.2 s, respectively. Furthermore, the morphological evolution of the CaIn2S4 ONBs and plausible UV/vis detection mechanism of the CaIn2S4 ONBs PD are discussed.

A colorimetric platform based on enzyme-inorganic hybrid nanoflowers was used for ultraviolet-visible detection of hydrogen peroxide (H 2 O 2 ). The hybrid nanoflowers were prepared via incubation at room temperature using horseradish peroxidase (HRP) and copper phosphate (Cu 3 (PO 4 ) 2 ) as the organic and inorganic components, respectively. HRP/Cu 3 (PO 4 ) 2 hybrid nanoflowers (HRP-HNFs) showed linear H 2 O 2 detection range from 100 nM to 100 μM, moreover, HRP-HNFs exhibited good selectivity for H 2 O 2 detection due to the specificity of HRP. In addition, HRP-HNFs have good reusability, excellent color stability and long-term storage stability, which indicate HRP-HNFs are promising for catalysis and biomedical applications.

Mixed-valence states can bring unexpected unique phenomena, especially novel anisotropic physics, due to structural asymmetry, which originate from the discrepant distribution of atoms with different valence. This study reports an unexploited mixed-valence-driven quasi-1D Sn II Sn IV S 3 crystal, which exhibits widely and distinctively anisotropic polarized-light absorption reaching ≈3.4 from the deep ultraviolet to near-infrared region (250–850 nm). The fabricated polarization-sensitive photodetectors based on highly air-stable Sn II Sn IV S 3 nanowires display strong linear dichroism among the UV–vis–NIR spectrum with responsivity exceeding ≈150 A W −1 . Furthermore, the devices are further constructed onto a flexible polyethylene terephthalate (PET) substrate and the photoresponse remains roughly unchanged after repeated bending. This work based on novel mixed-valence-driven quasi-1D ternary sulfide Sn II Sn IV S 3 excites interest in low-symmetry semiconductors for developing broadly spectral polarization-sensitive photodetectors with environmental stability and mechanical flexibility.

The development of effective Vis-sensitive photoinitiators for light-emitting diode (LED) polymerization is still an emerging challenge as LEDs are being developed into the predominant light sources. In this work, a series of new functionalized photoinitiators, containing thioxanthones and oxime-esters as functional groups, was designed and straightforwardly synthesized in two steps. The structures of the photoinitiators were studied using 1H NMR, 13C NMR, and high-resolution mass spectrometry. The conclusion of the photophysical properties indicated that the long wavelength absorptions from 360 nm to 405 nm made the investigated thioxanthone derivatives quite appealing as a valuable photoinitiator under UV-Vis LEDs. The structure–reactivity relationship was also studied in detail through real-time FTIR spectroscopy. A possible photolysis mechanism was expected based on further photolysis and online 1H NMR activities. With a proper molecular design, the new functionalized photoinitiators were synthesised straightforwardly and they displayed more advanced initiation abilities than their parent thioxanthone.

In order to make the most of solar energy, the development of efficient UV–Vis–NIR activated photocatalysts has attracted more and more attention. In this study, the UV–Vis–NIR broad spectrum activated photocatalysts La-doped BaBiO 2 Cl with abundant oxygen vacancies (OVs) were successfully prepared by solid state reaction . The experimental results and theoretical calculations revealed that La doping induced OVs in BaBiO 2 Cl, formed an intermediate level, extended the light absorption to the NIR region, and promoted carrier separation efficiency. Owing to the synergistic promotion effect, the optimal BaBiO 2 Cl–3%La exhibited obviously enhanced photodegradation rate, which was about 3.26 times higher than that of pure BaBiO 2 Cl under UV–Vis–NIR light irradiation . This work provides a resultful strategy for designing new full-spectrum-activated photocatalysts for environmental protection.

Formaldehyde is deemed to be an indispensable industrial product that has been widely applied in manufacture of resins, drugs, building materials, etc. It has been widely accepted that, nevertheless, residual formaldehyde will cause pathogen reactions, even leading to cancers like leukemia. Thus, a facile and efficient approach has been designed to achieve the determination of formaldehyde by ultraviolet and visible (UV–vis) spectrophotometry in liquid media. In detail, O-(carboxymethyl) hydroxylamine (C 2 H 5 NO 3 ·0.5HCl) is chosen as the detection reagent for the specific recognition of formaldehyde on account of its unique aminooxy (-O-NH 2 ) which can react with formaldehyde to form oxime bonds (O-N CH 2 ), accompanied with the only by-product of H 2 O. Likewise, this simple and sensitive detection approach based on the chemical detection reagent C 2 H 5 NO 3 ·0.5HCl can also be applied to the determination of other aldehyde homologs with carbonyl groups including acetaldehyde, acetone, benzaldehyde, 1, 4-phthalaldehyde. As a result, all the UV absorbances of analytes display remarkable linear detection relationships. The limits of detection (LOD) and limits of quantitation (LOQ) values are in the range of 0.03–1.16 ppm and 0.03–5.81 ppm respectively, with RSDs of 3.27–3.75 %, evidencing the feasibility of our method to determine formaldehyde and its homologs by UV–vis spectrophotometry and auspicious prospects of practical applications.

Here, we combined experimental measurements and DFT calculations to study UV–vis absorption spectra. DFT calculations of azobenzene and its derivatives proved useful for estimation of experimental spectra with near one-to-one correspondence. Calculation results show that substituents have no obvious effect on the coplanarity of benzene rings and N N bond. Potential energy surfaces were calculated for DHA and DEA. In the ground state, the inversion pathway was found to be preferred. A conical intersection was found between the ground and first excited states along the rotation pathway, indicating that the rotation mechanism is favored in the first excited state for DHA and DEA. UV–vis spectra of DHA and DEA were calculated by TD-DFT. Compared with azobenzene, the calculated wavelength of maximum absorption of DHA- trans and DEA- trans has red shift in UV–vis absorption spectra, which are in reasonable agreement with the experimental data.

Primaquine (PMQ), an important anti-malarial drug, has been recommended by the World Health Organization (WHO) for the treatment of life-threatening infections caused by P. vivax and ovale. However, PMQ has unwanted adverse effects that lead to acute hemolysis in patients with glucose-6-phosphate dehydrogenase (G6PD) deficiency. There is a need to develop simple and reliable methods for PMQ determination with the purpose of dosage monitoring. In early 2019, we have reported an UV-Vis and naked-eye based approach for PMQ colorimetric quantification. The detection was based on a Griess-like reaction between PMQ and anilines, which can generate colored azo products. The detection limit for direct measurement of PMQ in synthetic urine is in the nanomolar range. Moreover, this method has shown great potential for PMQ quantification from human serum samples at clinically relevant concentrations. In this protocol, we will describe the technical details regarding the syntheses and characterization of colored azo products, the reagent preparation, and the procedures for PMQ determination.

Neuromorphic vision sensors capable of multispectral perception and efficient recognition are highly desirable for bioretina emulation, but their realization is challenging. Here, we present a cocrystal strategy for preparing an organic nanowire retinamorphic vision sensor with UV–vis–NIR perception and fast recognition. By leveraging molecular-scale donor–acceptor interpenetration and charge-transfer interfaces, the cocrystal nanowire device exhibits ultrawide photoperception ranging from 350 to 1050 nm, fast photoresponse of 150 ms, high specific detectivity of 8.2 × 1012 Jones, and responsivity of 15 A W–1, as well as retina-like photosynaptic plasticity behaviors. Utilizing the sensor nerve and convolutional neural network, the architecture achieves 90% accuracy in recognizing colorful images. The cocrystal design offers an effective method for constructing nanowire photosynases with high performance in artificial visual systems.

In this work, multiple heterojunction Ag/Bi/BiOCl 0.8 Br 0.2 photocatalysts with novel porous micro-flower structure were fabricated via a facile one-step solvothermal route and characterized systematically. The TEM and HRTEM images clearly showed the heterogeneous nanostructures at the interface between Ag/Bi and BiOCl 0.8 Br 0.2 . The as-prepared Ag/Bi/BiOCl 0.8 Br 0.2 composites displayed a strong optical absorption in the region of 250–1500 nm, especially in the unexploited near infrared region which accounts for most of the sunlight. The multiple heterojunction photocatalyst exhibited an outstanding photocatalytic activity for the degradation of Rhodamine B under the UV, visible and NIR light irradiation, respectively. The highly enhanced photocatalytic activity was attributed to the synergistic effects, including the reduced band gap, the surface plasmon resonance effect, efficient charge separation of photo-generated electron-holes. On the basis of the radical species trapping experiments, the holes and superoxide radicals were confirmed to be the mainly active species involved in the degradation of Rhodamine B under the NIR light irradiation. This study provides a novel strategy for designing highly performance plasmonic photocatalysts under the whole solar light irradiation.

The integration of the KHCO 3 fed bipolar membrane (BPM) electrolyzer with KOH based CO 2 capture enables directly in situ conversion of captured CO 2 into valuable carbonaceous products, eliminating costly CO 2 recovery and compression steps. Even this integrated BPM system assembly holds promise, the critical lack of CO 2 adsorption intermediate species tracking necessitates the development of a monitoring platform. This work pioneers a novel dual-modal strategy employing simultaneous indicator-based sensing with in situ UV-Vis spectroscopy, achieving real time visualization of triphasic dynamics during integrated CO 2 capture-regeneration-conversion. Within this synergistic process involving Ar-saturated KHCO 3 decomposition, and electrochemical reduction, an etched indium (In) catalyst achieves 50% formate Faradaic efficiency (FE) at -1.1 V vs. RHE. The synergistic application of these complementary in situ diagnostics unlocks fundamental mechanistic insights into integrated CO 2 capture and conversion systems, establishing them as critical enablers for advancing efficient and scalable electrochemical CO 2 valorization.

Recent breakthroughs in three-dimensional (3D) printing of glass have enabled precise shaping of glass structures from macro to microscale while retaining their excellent physical and chemical properties. However, current functional developments in 3D printed glass primarily focus on leveraging its intrinsic optical transparency, with limited exploration of photonics application. 3D-printed glass functionalized by quantum dots (QDs) will hold great promise for creating desired photonic functional macro- and microstructures. However, voxel-precision customization of photonic functions in 3D printed glass by the monodispersed and size-controlled QDs is fundamentally conflict with the high-temperature sintering process required in 3D printed glass. Here, we present a simple, cost-effective method for creating a library of QDs functionalized 3D-printed glasses with tunable UV-VIS-IR photoluminescence (PL) by printing nanoporous glass (NG) followed by low-temperature nanoscale engineering of QDs growth. The integration of uniform and size-controlled QDs imparts 3D printed glass with fine tuning in composition, architecture, and photonic functionalities, while nanoscale engineering of the micro-environment enables precise tailoring of various QDs with enhanced optical performance and stability. This universal approach establishes a benchmark for 3D-printed functional glasses with advanced photonic capabilities.
