Optically transparent pressure-sensitive adhesives (PSAs) present several challenges. Conventional PSAs typically improve cohesive strength through chemical crosslinking; however, this approach not only reduces adhesion but also diminishes light transmittance. In this study, we explored hydrogen bonding crosslinking as a replacement for conventional chemical crosslinking and successfully synthesized the crosslinker UPyHCBA, which contains UPy units capable of forming self-complementary dimers through quadruple hydrogen bonds. A transparent acrylic PSAs incorporating the UPyHCBA monomer was then synthesized via solution polymerization. By modifying the ratio of UPyHCBA, we thoroughly investigated the impact of multiple hydrogen bonds on the molecular weight distribution, adhesive properties, thermal properties, light transmission, rheological behavior, and photoluminescence spectral properties of a specific optically transparent pressure-sensitive adhesive (PSAs).

One of the most important limitations to the development of photocatalytic process is the light damping in the reaction medium, as described by the Beer-Lambert Law. To address this issue, we developed a new approach by 3D printing the silica glasses to extend the light transmission. We first compared and selected the photosensitive components, and then regulated the debinding and sintering procedure based on the thermogravimetry data. The 3D printed transparent silica cylinders were used as catalyst carriers in a packed bed micro photocatalytic reactor (MPR) for the methylene blue degradation. We also studied the catalyst support using opaque Al 2 O 3 , and a catalyst suspension system for comparison. The results indicated that the use of printed silica as carriers significantly enhanced the reaction efficiency of the MPR. The once-coated MPR demonstrated a remarkable degradation efficiency of 91.4 % with a short residence time of just 9.7 s. This improvement was attributed to the high transparency of silica, which extended the permeation of UV light within the system. Finally, we investigated the scale up effect, which demonstrated that size effects and mass transfer played crucial roles in the MPR.

The high photoluminescence quantum yield, wide color tunability and narrow bandwidth of perovskite nanocrystals make them favorable for light source and display applications. Here, highly transparent green-light-emitting devices (LEDs) using inorganic cesium lead halide perovskite nanocrystal films as the emissive layer are reported. The effect of multilayered nanostructured transparent electrode on optical properties and performance within the LEDs is investigated by fine tuning layer thickness. The results show that the light transmission in visible region can be enhanced with this nanostructured film. These LEDs exhibited a high transmittance (average 73% over 400–700 nm) and high brightness of 2640 and 1572 cd m −2 for indium-doped tin oxide (ITO) cathode and MoO x /Au/MoO x anode sides, respectively.

An antireflection (AR) film on the surface of the photovoltaic glass can significantly improve the photoelectric conversion efficiency of solar cells. However, AR films prepared by a facile and low-cost sol-gel method usually exhibit poor mechanical properties , which limits their applications. Herein, hexamethoxy methyl melamine resin (CYMEL 303LF) was employed as a pore-forming agent in the sol and sacrificial template to prepare porous SiO 2 film on glass by a facile sol-gel method and subsequent heat treatment. The obtained SiO 2 film showed a high solar transmittance increase of 3.24% in the wavelength range of 380–1100 nm and a good hardness of H when the dosage of CYMEL 303LF is 10 wt%, the short circuit current density and photoelectric conversion efficiency of the solar cell are increased respectively by 1.44 mA/cm 2 and 1.08%, compared with the substrate, which is better than most SiO 2 films in the previous works. With increasing the dosage of CYMEL 303LF from 0% to 12%, the solar transmittance gain was increased at first and then decreased, while the film hardness was decreased straightly. This was probably because that the introduction of CYMEL 303LF can facilitate the formation of more pores in the SiO 2 film, leading to a decrease in the refractive index and film adhesion. Therefore, this work can provide a facile method to prepare high-performance SiO 2 as AR film for solar cells.

X-ray luminescence computed tomography (XLCT) is an emerging hybrid imaging modality in optical molecular imaging, which has attracted more attention and has been widely studied. In XLCT, the accuracy and operational efficiency of an optical transmission model play a decisive role in the rapid and accurate reconstruction of light sources. For simulation of optical transmission characteristics in XLCT, considering the limitations of the diffusion equation (DE) and the time and memory costs of simplified spherical harmonic approximation equation (SPN), a hybrid light transport model needs to be built. DE and SPN models are first-order and higher-order approximations of RTE, respectively. Due to the discontinuity of the regions using the DE and SPN models and the inconsistencies of the system matrix dimensions constructed by the two models in the solving process, the system matrix construction of a hybrid light transmission model is a problem to be solved. We provided a new finite element mesh regrouping strategy-based hybrid light transport model for XLCT. Firstly, based on the finite element mesh regrouping strategy, two separate meshes can be obtained. Thus, for DE and SPN models, the system matrixes and source weight matrixes can be calculated separately in two respective mesh systems. Meanwhile, some parallel computation strategy can be combined with finite element mesh regrouping strategy to further save the system matrix calculation time. Then, the two system matrixes with different dimensions were coupled though repeated nodes were processed according to the hybrid boundary conditions, the two meshes were combined into a regrouping mesh, and the hybrid optical transmission model was established. In addition, the proposed method can reduce the computational memory consumption than the previously proposed hybrid light transport model achieving good balance between computational accuracy and efficiency. The forward numerical simulation results showed that the proposed method had better transmission accuracy and achieved a balance between efficiency and accuracy. The reverse simulation results showed that the proposed method had superior location accuracy, morphological recovery capability, and image contrast capability in source reconstruction. In-vivo experiments verified the practicability and effectiveness of the proposed method.

Dynamic transparent-opaque transition behavior endows the stimuli-chromic materials with the solar modulation capability. However, these materials commonly involve the high manufacturing cost and complexity, the additional consumption of electric energy for solar modulation, or the weak effectiveness of light management. Herein, we develop a low-cost yet broadband light management sodium carboxymethyl cellulose-caging-poly(N-isopropylacrylamide) thermochromic composite (i.e., CMC/PNIPAM), where the nanoscale-skeleton CMC molecules well cage the PNIPAM molecules, which enables the homogeneous dispersion and sufficient distribution of the PNIPAM nanogels in the system. The CMC/PNIPAM features the excellent solar-modulation capability (including optical transmittance modulation of 68.17% and infrared transmittance modulation of 48.50%) and a low phase temperature of 30 °C, as well as the long-term stability of dynamic transparent-opaque transition. Such merits of the broadband light management, low cost, simply fabrication as well as scaling up, make the CMC/PNIPAM function as a promising candidate for the energy-saving buildings and construction.

X-ray imaging requires effective light transmission through scintillation screens. However, solid or solution-based scintillators suffer from photon scattering and attenuation. While prior efforts have focused on improving light extraction in solid-state scintillators through nanostructuring or optical engineering, challenges remain in mitigating internal scattering losses. Here, we report a liquid scintillator-based strategy that eliminates light scattering by exploiting in-situ coordination between lanthanide ions and ionic liquid ligands. This coordination chemistry ensures high structural homogeneity and optical transparency. Combined with self-absorption-free lanthanides, this approach achieves over 93% scintillation light transmittance, boosting X-ray imaging spatial resolution to 26 lp mm -1 within a 1 mm scintillation screen. Our scintillators exhibit long-term stability and environmental compatibility, leveraging the inherent properties of ionic liquids for sustained and biocompatible X-ray imaging. Their fluidic and shape-adaptive nature enables the development of convex and zoom scintillation lenses, facilitating uniform omni-angle X-ray detection and in-situ zoom X-ray imaging. Qiu et al. report an intrinsic liquid scintillator which eliminates the light scattering by exploring in-situ coordination between lanthanide ions and ionic liquid ligands. The liquid scintillator is biocompatible with high uniformity for omni-angle X-ray detection. Convex scintillation lens is demonstrated for enlarged X-ray imaging.

Our daily electromagnetic environment is becoming increasingly complex with the rapid development of consumer electronics and wireless communication technologies, which in turn necessitates the development of electromagnetic interference (EMI) shielding, especially for transparent components. We engineered a transparent EMI shielding film with crack-template based metallic mesh (CT-MM) that shows highly homogeneous light transmission and strong microwave shielding efficacy. The CT-MM film is fabricated using a cost-effective lift-off method based on a crackle template. It achieves a shielding effectiveness of ~26 dB, optical transmittance of ~91% and negligible impact on optical imaging performance. Moreover, high–quality CT-MM film is demonstrated on a large–calibre spherical surface. These excellent properties of CT-MM film, together with its advantages of facile large-area fabrication and scalability in processing on multi-shaped substrates, make CT-MM a powerful technology for transparent EMI shielding in practical applications.

Graphical Hydrogels with gradient opaque-transparent transition thermochromic temperature from 5 °C to 53 °C were prepared and the accuracy was controlled at 1 °C. The thermochromic property was regulated by the aggregation state of sodium dodecyl sulfate micelles by adding potassium tartrate hemihydrate and cations. The thermochromic hydrogel can serve for smart window and temperature detector/monitor. In recent years, the thermochromic hydrogel was acted as suitable sandwiching material to adjust light transmission. However, to accurately control the thermochromic temperature in a wide range still was a significant challenge. Here, a simple method was explored to prepare hydrogels with gradient opaque-transparent transition thermochromic temperature from 5 °C to 53 °C, which was regulated by the aggregation state of sodium dodecyl sulfate micelles by adding potassium tartrate hemihydrate and cations. Using Li + , Na + , and K + as cations, the accuracy was controlled at 1 °C. Moreover, the transmittance of the hydrogel was not changed when the thermochromic temperature was adjusted. As a result, an intelligent window was fabricated by utilizing thermochromic hydrogel as a sandwiching layer into the outer glass layers, which could effectively and stably regulate the visible and infrared light. The temperature monitors/detectors were also designed, which showed excellent temperature monitoring/detecting ability. Therefore, this low-cost, high-efficient, large-scale prepared thermochromic hydrogel provided more potential for intelligent temperature devices.
