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}

In this study, copper-halide (TBP)2Cu4Br6 (TBP+ = C16H36P+) single crystals are synthesized using a cooling crystallization method, which exhibits efficient dual-band emissions (542 and 708 nm), large Stokes shifts (282 and 330 nm), and a high photoluminescence quantum yield (PLQY) of 92.7% for 542 nm. These exceptional properties are attributed to the unique 0D structure of (TBP)2Cu4Br6 single crystals, which facilitates the formation of two different self-trapped excitons (STEs). Furthermore, based on (TBP)2Cu4Br6, a multi-mode and multi-color digital anti-counterfeiting system integrated is designed with Morse code information encryption, demonstrating promising applications in information security and anti-counterfeiting.

On the contrary, it isn't considered as a promising fluorescent material due to the inefficient radiative recombination of electron-hole pairs. Here, efficient and multicolor-emitting g-CN phosphors are presented by integrating donor-acceptor substituents in order to replace the expensive rare earth-based phosphors. By incorporating phenyl as a donor and benzonitrile as an acceptor, the aromatic groups enhance the structural rigidity of g-CN and improve the photoluminescence (PL) efficiency; meanwhile, the donor-acceptor extends the π-conjugated system of g-CN, promotes the electron delocalization and results in tunable PL spectra. As a result, the donor-acceptor substituted g-CN materials exhibit blue to yellow light emission and reach a record photoluminescence quantum yield (PLQY) of 57%. A white light-emitting diode is fabricated by combining the modified g-CN phosphors and commercial 450 nm blue chips, which produce a bright white light emission with chromaticity coordinates of (0.34, 0.32). The findings provide a rational design for a high-performance g-CN emitter and highlight the potential applications of g-CN in optoelectronic devices and indoor lighting.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 13","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143905402","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}

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.

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}
