Abstract This work presents a novel and highly secure anticounterfeiting strategy based on high entropy upconversion perovskite halides with thermally responsive multicolor emissions excited by a single laser. The perovskite halides are doped with rare earth cations and oxygen anions simultaneously and form the high entropy crystal structure by using a solid‐state reaction method. The color‐shifting emissions stem from luminescent kinetics transformation from energy transfer upconversion at low temperature to excited state absorption at high temperature. The multicolor emissions can also be trigged by the 975 nm laser heating effect. The results indicate the great potential of the high entropy upconversion perovskites for anticounterfeiting applications with a convenient recognition method.

Abstract Nano/micro‐plastics pollution is an emerging global concern. A variety of biodegradable polymers have been synthesized to enhance the degradation of plastic materials and thereby avoid their accumulation in the environment. However, even biodegradable polymers can accumulate in environments under specific conditions and present a potential hazard. Here, antimony sulfide‐based microrobots decorated with magnetite nanoparticles are designed for microplastics degradation. The propulsion of microrobots is enabled by two independent orthogonal physical modes via magnetic field and via light irradiation. Due to phoretic interactions, the microrobots exhibit affinity toward poly(3‐hydroxybutyrate) (PHB) and poly(lactic acid) (PLA) microplastics, which enables subsequent transport of the microplastics in a transversal rotating magnetic field. The photocatalytic activity of Sb 2 S 3 quantum material provides microrobots with the ability to degrade the microplastics under UV light irradiation in the “on‐the‐fly” regime without the need for any fuel. This proof‐of‐concept work shows efficient capture, transport, and photocatalytic degradation of microplastics and paves the way toward their elimination, especially in water environments.

Photocatalytic Microplastics “On‐The‐fly” Degradation via Motile Quantum Materials‐Based Microrobots

基于可移动量子材料的微型机器人实现光催化微塑料“飞行中”降解

Abstract Optogenetics has been widely applied as a cell‐specific technique with high temporal resolution for the modulation of neural circuitry in vivo, offering potential novel treatments for neuropsychiatric diseases. However, to date, the most widely used optogenetics waveguides remain silica optical fibers, which may lead to a mismatch in the mechanical properties between the implants and neural tissues. To resolve this issue, alginate‐polyacrylamide hydrogel optical fibers can be fabricated in a simplified one‐step process, and they show significantly improved characteristics for the in vivo optogenetic applications, including low light‐propagation loss and Young's modulus, and high stretchability. After the expression of AAV‐CaMKIIα‐ChR2‐mCherry, blue light pulses are delivered into hippocampus using a hydrogel‐optrode array, and frequency‐dependent neural responses can be observed. Moreover, optogenetic stimulation through the chronic implanted hydrogel optical fibers in the primary motor cortex can considerably modulate the animal's behavior. Hydrogel fibers significantly alleviate tissue response at the implant/neural interface, compared with that observed using the silica optical fibers. Taken together, the results of this study demonstrate the feasibility and advantages of the hydrogel optical fiber use for chronic optogenetic modulation in free‐moving animals. Hydrogel implant use may allow the development of novel therapeutic strategies for the treatment of neuropsychiatric disorders.

Abstract With the rapid growth in intelligent metasurfaces in the recent years, deep learning has attracted attention to transform the ways in which metasurfaces are simulated and designed. The unique advantages of deep learning lie in the powerful data‐driven modality, which allows a computational model to learn useful information using hierarchically structured layers. Among the various successful examples, there are forward and inverse designs. However, such designs are inherently data‐hungry. Thus, the data utilization efficiency must be maximized, and green metasurface design must be achieved. Here, the authors propose heterogeneous transfer learning to allow transferrable and data‐efficient metasurface design. The key to this method is a flexible network framework, which integrates feature augmentation and dimensionality reduction. The concept is demonstrated through three scenarios, i.e., metasurfaces with different parameterizations, different physical sizes, and completely different geometries, where the relative error reduction reaches up to 50%. Furthermore, an inverse metasurface design is proposed, which combines the forward predicted network and heuristic algorithm. This work considerably reduces the workload on data collection and overcomes the limitation that previous works only focused on fixed physical structures. The authors have also envisioned a “global metasurface gene bank,” in which researchers can freely “withdraw and save data” for various applications.

Abstract P–n junctions based on 2D materials can be achieved using a selective doping technique, while such a method is challenged by the complex fabrication process. Here, a facile van der Waals (vdWs) structured p–n heterojunction is demonstrated by simply transferring an n‐type multilayer α‐In 2 Se 3 (direct bandgap) on a p‐type ultra‐thin WSe 2 nanosheet. The vdWs stacked photodetector with an improved type‐II band alignment not only realizes a broadband spectral response from visible to near infrared (405–905 nm), but also operates well with a diode‐like behavior. This behavior is further confirmed by the high‐resolution scanning photocurrent mapping. As a result, the as‐fabricated device exhibits a short response time (&lt;120 µs) and a high responsivity of 1.84 A W −1 under 520 nm laser illumination. Accordingly, an underwater optical communication system based on the WSe 2 /α‐In 2 Se 3 p‐n heterojunction photodetector is demonstrated, which is promising for next‐generation high‐performance and low‐power detection applications.

Abstract Metasurfaces have become one of the most prominent research topics in the field of optics owing to their unprecedented properties and novel applications on an ultrathin platform. By combining graphene with metasurfaces, electrical tunable functions can be achieved with fast tuning speed, large modulation depth, and broad tuning range. However, the tuning efficiency of hybrid graphene metasurfaces within the short‐wavelength infrared (SWIR) spectrum is typically low because of the small resonance wavelength shift in this wavelength range. In this work, through the integration of graphene and silicon metasurfaces that support quasi‐bound states in the continuum (quasi‐BIC), the critical coupling as well as transmittance spectrum tuning is experimentally demonstrated. The spectrum tuning is substantial even with less than 30 nm resonance wavelength shift thanks to the high quality factor of quasi‐BIC metasurfaces. The tunable transmittance spectrum is measured using Fourier transform infrared spectroscopy (FTIR) with a modified reflective lens to improve the accuracy, and the electrical tuning is realized utilizing the “cut‐and‐stick” method of ion gel. At the wavelength of 3.0 µm, the measured transmittance change (Δ T = T max − T min ) and modulation depth (Δ T / T max ) can reach 22.2% and 28.9%, respectively, under a small bias voltage ranging from −2 to +2 V. This work demonstrates an effective way of tuning metasurfaces within the SWIR spectrum, which has potential applications in optical modulation, reconfigurable photonic devices, and optical communications.

Abstract Flexible photodetectors have garnered significant attention in recent years due to their potential applications in emerging fields such as artificial intelligence, medical diagnostics, and wearable devices. Quasi‐2D perovskites exhibit remarkable optoelectronic properties, excellent environmental stability, and mechanical flexibility, making them promising materials for flexible photodetectors. Achieving precise control over the morphology of these materials is crucial for enhancing device performance. In this study, periodic wrinkle structures are introduced into quasi‐2D perovskite films by applying pre‐stretching stress to a flexible substrate. These results indicate that these ordered wrinkle structures facilitate grain movement during formation, enabling smaller grains to fill pores and surround larger grains. This process leads to a denser film with a mixed 2D‐3D phase architecture, enhancing charge transfer efficiency and prolonging carrier lifetime in the perovskite films. Consequently, the responsivity of the resulting flexible perovskite photodetector significantly increased, reaching 86.7 A W −1 , which is 2.5 times higher than that of the unstretched device. Furthermore, the wrinkled structures enhanced mechanical tolerance, allowing the photodetector to retain 80% of its initial responsivity even after 10 000 stretching cycles. These findings highlight the potential of wrinkled structures to significantly enhance the performance of flexible perovskite optoelectronic devices.

Abstract Due to the wavelength‐dependent absorption, narrow bandgap semiconductors show potential application in ultraviolet (UV) photodetection by thinning. However, the limited absorption in the thinner layer retards their application in high‐performance photodetection. In this paper, the fabrication of an asymmetric Fabry–Pérot (F–P) structure is reported by planar stacking of InSe layer, Al 2 O 3 spacer, and Al back reflector. For the selective absorption enhancement in UV region, the Al 2 O 3 thickness is optimized to be 39 nm by finite element method (FEM). The device presents a peak response at 265 nm illumination, showing the photo‐to‐dark current ratio ( I light / I dark ) of 719. Responsivity ( R ) and photoconductive gain ( G ) reach 11.7 A W −1 and 54.7 at the weak light intensity of 0.03 mW cm −2 , respectively, which are two orders of magnitude higher than those of the device without the asymmetric F–P structure, revealing the remarkably enhanced absorption. This work shows well compatibility with the manufacturing processes for 2D semiconductor‐based photodetectors and provides a simple and versatile strategy for the application of 2D narrow bandgap semiconductors in high‐performance UV photodetectors.

Abstract The low cost and fine‐tunability of the luminescence of copper nanoclusters make them attractive candidates for opto‐electronic, imaging, and sensing applications; their stability, and a precise understanding of the structure–function correlations however, continue to be challenging. A comprehensive chemical etching strategy is developed to synthesize orange, blue, and cyan emitting nanoclusters from a single source of ultrasmall copper nanoparticles; high quantum yields up to ≈34% are realized. Steady state and time‐resolved spectroscopy, electron microscopy, high resolution mass spectrometry, and computational modeling provide critical mechanistic insight into the polychromatic luminescence. A facile method for the fabrication of polymer nanocomposite thin films that sustain and stabilize the luminescent nanoclusters is presented. A subtle variation of the etching strategy without the need to admix multiple components, provides white luminescent thin films with Commission Internationale de l'éclairage (CIE) coordinates, x = 0.35, y = 0.33. The highlights of this work are i) the simple solution synthesis of stable, uniform, and pure ultrasmall Cu nanoparticles, ii) their chemical etching by subtle variations in an optimized protocol to produce highly luminescent, polychromatic nanoclusters, including white‐emitting ones, iii) stabilization of the bright luminescent systems in nanocomposite thin films, and iv) a detailed analysis of the luminescence tuning.

Abstract Dual‐function devices are being used in smart wearable electronics and human‐machine interaction because of their special functions. In this study, three modified PPIAn2N‐based emitters— PPIAn2N‐CH 3 , PPIAn2N‐CN , and PPIAn2N‐F —are synthesized and applied them in dual‐functional devices, specifically organic light‐emitting diodes (OLEDs) and UV organic photodetectors (UVOPDs). Each of these molecules exhibits hybridized local and charge transfer (HLCT) excited states, which results in blue emission both in solution and in thin films. However, the proportion of local excited (LE) states to charge transfer (CT) states differs among the molecules. The non‐doped OLED using PPIAn2N‐F displayed outstanding performance, emitting deep blue light at 456 nm, with a Commission Internationale de l'Éclairage (CIE) coordinate of (0.14, 0.14), and achieving a maximum external quantum efficiency (EQE) of 8.52%. Additionally, the PPIAn2N‐F ‐based OLED‐UVOPD demonstrated excellent UV detection capabilities, with a detectivity ( D * ) of 8.60 × 10 10 Jones. The device achieved a well‐balanced EQE/ D * ratio, indicating an optimal combination of luminescence efficiency and detection sensitivity. These findings underscore the potential of multifunctional devices operating in the blue emission spectrum, paving the way for advancements in dual‐functional OLED and UV detection technologies.
