This review categorizes and analyzes structural modifications across four key molecular architectures—pristine QAOs, phenyl-substituted QAOs, cyclized QAOs, and polynuclear QAOs—revealing their distinct impacts on full width at half maximum (FWHM), reorganization energy (λ), and excited-state dynamics. Notably, structural strategies such as R1 substitution, R4-R5 cyclization, and steric shielding with bulky groups like tert-butyl lead to enh anced molecular rigidity, suppressed vibrational relaxation, and record-narrow emissions (FWHM ≤ 13 nm). Furthermore, donor-acceptor tuning across the series enables precise the highest occupied molecular orbital (HOMO) – the lowest unoccupied molecular orbital (LUMO) separation, balancing short-range charge transfer with emission color control. Emission statistics, fluorescence lifetime analysis, and device performance metrics are presented, consolidating structure-property relationships across >100 reported derivatives. This review provides design principles grounded in both theoretical insight and empirical evidence, offering a roadmap for the development of next-generation MR-TADF materials with high color purity, stability, and efficiency. These findings highlight the N/C = O MR core as a versatile and promising scaffold for advanced display technologies.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 28","pages":""},"PeriodicalIF":7.2,"publicationDate":"2025-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145196888","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, exciton quenching at the interface between quantum dots (QDs) and ZnO NPs and unfavorable band alignment hinder the performance of QLED devices. In this study, a straightforward and versatile approach is introduced to fabricate high-performance QLED by incorporating Polyacrylamide (polyNIPAM) with ZnO NPs. The resulting QD and hybrid-ZnO NPs films achieved a photoluminescence quantum yield (PLQY) of 57.8% and a recombination rate of 80.07%. Compared to conventional ZnO-based QLEDs, the hybrid approach led to a significant improvement in external quantum efficiency (22.34%), maximum brightness (97 593 cd m−2), and a narrow full-width at half maximum (FWHM) of 22.3 nm. The hybrid ZnO NPs exhibited favorable energy levels for electron injection, promoting exciton recombination while minimizing charge diffusion losses at the QD/ZnO NP interfaces. These findings highlight the potential of polyNIPAM-functionalized ZnO NPs for scalable, high-performance QLED fabrication.

Currently, challenges such as difficulties in large-area preparation, high costs, and degradation of electrochromic performance over time have hindered their widespread application. 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. Utilizing UV light to restore the performance of these WO3-PB ECDs promotes sustainable and environmentally friendly development, highlighting their important practical value.","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":"145196728","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}

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. This approach provides a scalable, low-cost, and eco-friendly strategy for developing high-performance, high-speed, and high-stability infrared photodetection systems.","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":"145196702","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 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°.
