Metasurfaces are widely used in polarized photodetectors, while the responses for different polarization incidences follow a determinable and consistent correspondence. In this paper, an electrically tunable polarization photodetector composed of MoTe2 and gold metasurface is proposed for on-chip polarization-sensitive near-infrared (900–1200 nm) detection. Through contact engineering and electro-tuning, highly-tunable Schottky barriers are achieved. This enables the modulation of photoelectric conversion via the excitation of surface plasmon polaritons, which in turn allows for continuous adjustment on the degree of linear polarization of a settled metasurface ranging from 0.2 to an ultimate value of 1.0. The results outline a paradigm to achieve a polarization-dependent electrically tunable response, which is promising for on-chip information processing in integrated optics.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 9","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143688786","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, developing scintillators capable of time-lapse imaging under extreme conditions, such as high-temperature environments, remains a formidable challenge. Herein, Tb3+-doped oxyfluoride glass ceramics (GCs) with exceptional scintillation performance and X-ray-induced persistent luminescence (PersL) are successfully fabricated. Remarkably, the luminescent intensities under ultraviolet and X-ray excitation are significantly enhanced by optimizing the Al2O3 content and inducing the precipitation of Na5Lu9F32 nanocrystals. The integral X-ray-excited luminescence intensity reaches 219.3% of that of Bi4Ge3O12. The GCs exhibit robust irradiation resistance even under high-power X-ray exposure. Real-time imaging based on GCs demonstrates a spatial resolution of 18 lp mm−1. Furthermore, the GCs display pronounced thermally stimulated PersL following X-ray excitation, attributed to the generation of Frenkel defects. This behavior facilitates the development of a time-lapse imaging technique with high-temperature visibility after X-ray irradiation, achieving an impressive spatial resolution of 14 lp mm−1, and allowing X-ray image storage for over 168 h. These findings underscore the immense potential of GC scintillators for advanced X-ray imaging applications, particularly in harsh environments.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 8","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143622756","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, developing structural color materials that exhibit vivid colors with minimal angular dependence is crucial for their practical application. In this study, spherical colloidal crystals (photonic balls) with bright colors and effectively suppressed angular dependence are developed using monodisperse high refractive index CeO₂ particles. To fabricate these photonic balls, CeO₂@PDA particles are synthesized by coating CeO₂ particles with polydopamine (PDA), a black component. The light-absorbing PDA coating on each particle uniformly reduces the multiple scattering of light to form a black background, allowing the CeO₂@PDA photonic balls to exhibit brilliant structural colors. Compared to SiO₂ particles photonic balls, which are widely studied in previous research, CeO₂@PDA photonic balls have a significantly reduced angular dependence of structural color hue due to their composition of materials with a higher refractive index. Additionally, the CeO₂@PDA photonic balls are heat-treated in a nitrogen atmosphere, transforming the polymer component on the particle surface into a black carbonaceous material with a higher refractive index. This process further reduces the angular dependence of structure color hues observed from the photonic balls and improves color vibrancy.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 9","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adom.202402863","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143690244","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}

Existing imaging tools often fail to reliably differentiate between ER-positive and ER-negative cancer cells. To address this limitation, two novel fluorescent probes, E2N and E2R, are synthesized by conjugating estradiol to styryl and rhodamine-based fluorophores using click chemistry. These probes are characterized by their photophysical properties, biocompatibility, and selective targeting of ER-positive cells. Cellular uptake studies demonstrate preferential internalization of E2N and E2R in ER-positive MCF-7, ZR-75-1, and T-47D cells, with minimal uptake in ER-negative MDA-MB-231, MDA-MB-468, and healthy COS-7 and NIH-3T3 cell lines. Kinetic studies reveal efficient and rapid uptake of E2N in ER-positive MCF-7 cells, while mechanistic investigations identified clathrin-mediated endocytosis as the receptor-mediated pathway for both probes. Localization studies further confirm their mitochondrial specificity in ER-positive cells, with E2R displaying higher mitochondrial selectivity. These findings underscore the potential of E2N and E2R as powerful tools for distinguishing ER-positive from ER-negative breast cancer cells. Their receptor-mediated targeting and precise imaging capabilities make them promising candidates for advancing breast cancer diagnostics and enabling more targeted therapeutic strategies.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 8","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143622757","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}

In this study, hierarchical microspheres (HMs) with a two-tier structure, composed of SiO2, TiO2-coated SiO2, BaSO4, or PNIPAM, are incorporated into PDMS-based composites. These microspheres feature larger spheres assembled from submicrometer-scale nanoparticles and are fabricated via microfluidics to enhance radiative cooling performance. SiO2 HMs not only boost visible light reflection and exhibit structural color through a photonic stop band but also achieve an average emissivity of 97.55% in the atmospheric window. Both experimental and simulated results show that HMs enhance the emissivity performance of the composite material compared with solid SiO2 microspheres of the same diameter. Additionally, applying TiO2 coating to SiO2 HMs further increases the overall emissivity to 98.05%. Incorporating BaSO4 HMs also increased the average visible reflectivity to 96.56%, while maintaining superior infrared emissivity at 97.58%. The inclusion of PNIPAM spheres enabled temperature-responsive transmissivity, with the composite materials containing PNIPAM and SiO2 HMs preserving high infrared emissivity in the atmospheric window. These HM structures exhibit excellent solar reflectivity and thermal emission, making them effective for radiative cooling.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 9","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143690285","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}

Most of the newly synthesized dyes show high dichroic ratios and order parameters, ensuring strong optical anisotropy and good alignment within the liquid crystal host mixture. The performance of individual dyes in smart window applications is evaluated, with transmittance changes observed under dynamic electric fields, demonstrating their potential for use in electrically tunable smart windows. To achieve full visible-light modulation, the combination of complementary absorption dyes is screened and an optimized mixture Mix-7 is obtained, which not only achieves full visible-light absorption coverage but also demonstrates smooth and dynamic transmittance modulation under varying voltages. Finally, a prototype smart window filled with Mix-7 is fabricated to validate the continuous tunability of dye-doped liquid crystal-based systems. Additionally, further introduction of a polarizer film significantly reduces the transmittance of the demo, especially in the OFF state which presents an almost completely dark state, highlighting the potential for automotive smart window applications.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 8","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143622561","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}
