A key challenge lies in the development of emitters that can simultaneously deliver high efficiency, narrowband emission, and strong circular polarization. Herein, we report three pairs of helical CP-MR-TADF compounds, M/P-PhCz-QAO, M/P-BFN-QAO, and M/P-BSF-QAO, in which N-phenylcarbazole, dibenzofuran, and dibenzothiophene units induce intrinsic helical chirality within a carbonyl/nitrogen-based MR-TADF framework.

When integrated into OLEDs, the devices achieve maximum external quantum efficiencies of up to 15.1% together with clear circularly polarized electroluminescence signals with gEL values on the order of 10−3.

This review examines the latest integration strategies, including wafer bonding, transfer printing, and additive manufacturing using multi-photon lithography, not as isolated techniques but as connected approaches for addressing these challenges. Advances in materials and post processing are described such as silica and ceramic conversion, improvements in metrology including refractive index and durability characterization, and emerging functionalities such as stimuli responsive 4D components, polarization control, photoluminescent elements, and integrated micro-optics. The discussion highlights performance tradeoffs between precision, throughput, and material properties, and shows how new processing and design methods extend the scope of photonic integration.

Conventional thermal control materials, characterized by static thermo-optical properties, often fail to meet the demands under dynamic thermal conditions. In this study, we achieve exceptional thermo-optical properties in AgNbO3-based ceramics (Ag1-xBix/3NbO3 with x = 0.20, ABN0.20), demonstrating a high emittance variation (Δε = 0.298) and temperature-stable absorptance (Δα = 0.046) across a broad temperature range. Through integrated experimental analysis and DFT calculations, we investigate the effects of doping on lattice structure, phase transition temperature, and thermo-optical properties. Key findings include: (i) The phase transition temperature decreases with decreasing ionic radius of the dopant, particularly that Bi3+ and Ta5+ ion doping significantly lowers the M1–M2 phase transition temperature, stabilizing the antiferroelectric phase near room temperature. (ii) Dopants effectively narrow the bandgap of AgNbO3, enhancing solar absorption. (iii) The d–p orbital hybridization between Ag(Nb)─O bonds governs emissivity through thermal disruption susceptibility. Strengthened hybridization expands the resonant area, thereby increasing infrared emission. These results demonstrate that orbital hybridization-mediated tuning in doped AgNbO3 ceramics offers a promising pathway for developing adaptive thermal control systems, particularly for applications requiring real-time emissivity modulation and solar-thermal regulation.\u0000 </div>","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"14 10","pages":""},"PeriodicalIF":7.2,"publicationDate":"2026-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147566348","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}
