However, most fabrication methods yield either grainy 2D perovskite films, microcrystalline powders, or microcrystals with highly irregular shapes. Here, a rapid and tunable recrystallization-based approach is presented to fabricate single-crystalline 2DLP microcrystals with lateral dimensions from few to hundreds of microns, rectangular shape and excellent thickness homogeneity, with which lateral size and thickness can be adjusted by the synthesis parameters. This method involves dissolving 2DLP powders in a solvent–antisolvent mixture carefully tuned close to saturation, followed by crystallization controlled via a mild thermal gradient and solvent evaporation. This protocol enables the straightforward synthesis of 2DLPs of diverse compositions and on a variety of substrates. Thanks to their regular shape, extremely flat surface and uniform thickness, these microcrystals show homogeneous emission over their entire surface, and behave as photonic cavities, sustaining confined modes and exciton-polaritons. Such advantageous properties, which in the future could be combined with size and position control, have the potential to boost the development of optoelectronic microdevices, where the single crystals are implemented as emitting or sensing pixels.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 27","pages":""},"PeriodicalIF":7.2,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/adom.202501276","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145111274","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During the photopolymerization, there is a transforfation of the precursor nanoclusters and the nanocomposite achieves a maximum photoluminescence quantum yield of ≈73% at 740 nm and 60% at the 850 nm emission peak. The photophysical characteristics of nanocomposite AuAgNCs@OSTE are examined at both ambient and low temperatures, revealing an improved radiative recombination mechanism through the interactions with polymer radicals. This high photoluminescence quantum yield near-infrared-emitting AuAgNCs@OSTE material, distinguished by a larger Stokes shift, is utilized to fabricate luminescent solar concentrators measuring 5 × 5 × 0.13 cm3. Experimental measurements are conducted to determine the absorption coefficient, reabsorption coefficient, absorption cross-section, and volume concentration of the device. Additionally, theoretical evaluations of waveguiding efficiency and power conversion efficiency are performed and compared with quantum dot-based alternatives. The findings indicate that the metal NCs@OSTE nanocomposite has the potential to function as a highly efficient, heavy-metal-free nanophosphor, demonstrating superior overall performance for semi-transparent luminescent solar concentrator devices and being suitable for a broad range of light conversion applications in the NIR spectrum.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 28","pages":""},"PeriodicalIF":7.2,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/adom.202501158","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145197026","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review distinctively highlights recent advancements in integrating photonic crystal structures into actuating materials, emphasizing three novel contributions compared to existing literature: comprehensive analysis of fabrication strategies, diverse stimulus-response mechanisms, and the design of innovative biomimetic devices. The uniqueness of this study lies in its detailed exploration of photonic crystal actuators fabricated from polymers, hydrogels, and cholesteric liquid crystals, responding to stimuli such as photo, temperature, humidity, magnetism, and biological factors, including myocardial cells. Furthermore, it critically discusses practical applications across various fields, including displays, mechanical manipulation devices, soft crawling and swimming robots, energy converters, and visual sensing technologies.

Despite their potential, achieving precise control over the structural and optical properties of these materials has remained a significant challenge, often requiring complex fabrication processes and post-lithography processing steps that limit scalability, sustainability, and practical implementation. In this work, upon the use of nanoimprinting of refractive index (NIRI) is reported to directly pattern mesoporous titania (pTiO2) and achieve localized, compression-based modulation of refractive index. Two formulations of sol-gel derived pTiO2 thin films are interrogated, revealing tunable refractive indices ranging from n ≈ 1.5 to n ≈ 2.2 at visible wavelengths in response to nanoimprinting-induced compression. Using a variety of micro-patterned stamps, the direct fabrication of planar diffractive and gradient index optics is demonstrated without any curing, etching, or post-lithography processing steps. These findings demonstrate that direct imprinting of pTiO₂ is a sustainable and effective method for controlling refractive index and fabricating optical devices, paving the way for future advancements in the development of compression-tuned optical materials and their diverse applications.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 27","pages":""},"PeriodicalIF":7.2,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/adom.202501401","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145111273","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
