A strategy incorporating a dual-phase nanocrystalline structure of WO3 and TiO2·H2O is proposed, in which specific synthesis parameters are precisely controlled to tailor the microstructure and composition of the films, enabling the fabrication of large-area WO3-PB ECD with UV-rejuvenation electrochromic performance. As a result, the as-prepared WO3-PB ECD exhibits an optical modulation of 75.6% and a remarkable cycle life exceeding 13,000 cycles. The electrochromic performance degradation caused by long cycles can be restored via UV irradiation.

Herein, novel Zn/MnO2 dual-electrodeposition-based smart windows are constructed utilizing near-neutral electrolytes (pH = 5.74). The devices broaden the light modulation range of MnO2 by reversible Zn electrodeposition, achieving a remarkable color change between transparent and neutral dark brown (chroma C* = 9.48). Furthermore, an iodide (I−) as a redox mediator is used to significantly prolong the devices’ cycling durability by promoting the dissolution of MnO2 and Zn. I− chemically reduces MnO2 to form Mn2+ and is oxidized to triiodide (I3−), I3− then spontaneously oxidizes Zn to form Zn2+ and is reduced back to I−, thus completing one mediator cycle. Consequently, the devices with the I− mediator exhibit impressive cycling durability (1,000 vs 60 cycles). Finally, the significant potential difference between the Zn and MnO2 electrodes endows the devices with excellent energy storage performance. The study offers a line of thought for developing novel multifunctional devices.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 28","pages":""},"PeriodicalIF":7.2,"publicationDate":"2025-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145196705","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, their performance is hindered by high dark current density and inefficient carrier extraction. Herein, ZnTe is introduced as a hole-transport layer (HTL) to reconfigure the band structure and fabricate a high-performance ZnO/(Bi,Sb)2Se3/ZnTe photodetector. By systematically tuning the ZnTe HTL thickness, a 53% enhancement in EQE (16.2% at 1300 nm) and a 50% reduction in dark current density (97.4 µA cm−2, at −0.5 V) are achieved compared to HTL-free devices. SCAPS simulation elucidates that the designed (Bi,Sb)2Se3/ZnTe heterojunction effectively suppresses electron backflow while enhancing hole extraction, thereby boosting performance. Therefore, the optimized device exhibits a notably fast response time (12/107.5 ns rise/fall) and a wide linear dynamic range (LDR, 96 dB). Additionally, unencapsulated devices retain 97.7% of their initial performance after 322 h of operating at 90 °C and withstand extreme annealing at 150°C, surpassing many state-of-the-art detectors.

However, most NTR emitters only cover a narrow band, which is unwanted for thermal energy utilization. Here, a material-informatics framework with a Bayesian optimization (BO) kernel is proposed for designing NTR emitters, which consists of multilayer epsilon-near-zero (ENZ) magneto-optical films on a metal bottom. The optimal structural parameters can be obtained within only 0.5% of all possible structures, demonstrating super-efficient optimization capability. Additionally, compared to the design method based on the Fresnel formula, the broadband nonreciprocity can be significantly enhanced, with the wavelength-averaged nonreciprocity improved by 80.4%, which can be attributed to the unequal electromagnetic power dissipation density and mismatched effective impedance at opposite angles. Furthermore, the effects of the dielectric layer, different incident angles, number of layers, and magnetic fields on BO-based nonreciprocal thermal emitters have been investigated. This study can further promote the development of broadband NTR and can be extended to multilayer structures containing magnetic Weyl semimetals.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 28","pages":""},"PeriodicalIF":7.2,"publicationDate":"2025-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145196704","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, most existing strategies for narrowband detection depend on spectral filtering either through saturable absorption, which requires active layers exceeding 500 nm, restricting the choice of materials for producing high-quality films, or cavity effects, which inherently introduce strong angular dispersion. Microcavity exciton-polariton (polariton) modes, which emerge from strong exciton-photon coupling, have recently been explored as an angular dispersion suppression strategy for organic optoelectronics. In this work, the first narrowband infrared polariton organic photodiode that combines angle-independent response with a record-high responsivity of 0.24 A W−1 at 965 nm and –2 V is presented. This device, featuring a 100-nm-thin active layer comprising a non-fullerene acceptor, exhibits a detection mode with a full-width at half-maximum of less than 30 nm and a marginal angular dispersion of under 15 nm across ±45°.

Herein, the origin of this luminescence switching is elucidated through a combined theoretical and experimental study of a prototypical MR emitter, quinolino[3,2,1-de]acridine-5,9-dione (QAO). While QAO displays TADF in 9,9′-(1,3-phenyl)di-9H-carbazole (mCP) film but switches to RTP in benzophenone (BP) crystal. Multiscale simulations reveal that BP-induced conformational distortion triggers a conversion from S1(π, π*) to S1(n, π*). This change i) introduces a dipole-forbidden transition, leading to >300-fold reduction in radiative decay rate; ii) and largely enhances the spin–orbit coupling of S1 → T1, accelerating the intersystem crossing (ISC) rate by five orders of magnitude, with the aid of enhanced vibronic coupling. Additionally, the singlet-triplet energy gap shows a tiny change with values of ≈0.2 eV, supporting the reverse ISC for triplet exciton harvesting. As a result, the bright TADF of QAO in mCP film is converted to RTP in BP crystal, with theoretical predictions showing excellent agreement with experimental emission spectra and RTP lifetimes. These findings provide fundamental insights into the molecular design of high-performance MR-based RTP materials, paving the way for next-generation organic optoelectronic applications.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 24","pages":""},"PeriodicalIF":7.2,"publicationDate":"2025-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144897628","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
