Diamond-based photodetectors are emerging as ideal candidates to replace traditional silicon-based detectors for high-selectivity and radiation hardness. Here, a vertical Schottky photodiode based on p-type high-quality single-crystal diamond is presented. By modulating the diamond surface band structure and band alignment, an ultra-short response time of only 15 ns, and a photo-to-dark current ratio greater than 105 under the reverse bias are achieved. It is the first time to study the spectral response of the diamond photodiode in the range of 260 nm to as low as 120 nm under vacuum conditions, exhibiting an ideal selective responsivity and excellent imaging capability in the VUV range. This device holds promising prospects for coupling with optomechanical systems to enable a multidimensional detection of solar VUV radiation, including imaging and spectrum.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 7","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143555116","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}

The temporal modulation of the nanostructures constitutes an additional degree of freedom to control their scattering properties on demand and in a reconfigurable manner. However, these additional parameters create a vast design space, raising challenges in identifying optimal designs. Therefore, tools from the field of photonic inverse design must be used to optimize the degrees of freedom of the system to facilitate predefined optical responses. To further develop this field, here a differentiable transition (T-) matrix-based inverse design framework is introduced for dispersive time-varying nanostructures. The electron density of the material of the nanostructures is modulated non-adiabatically as a generic periodic function of time. Using the inverse design framework, the temporal shape of the electron density can be manipulated to reach the target functionality. This computational framework is exploited, exemplarily, in two instances. First, the decay rate enhancement of oscillating dipoles near time-varying spheres is controlled on demand. Second, using spatiotemporal metasurfaces, a system supporting asymmetric transmission of light at visible frequencies is designed. This work paves the way toward programmable spatiotemporal metasurfaces and space-time crystals for a future generation of reconfigurable functional photonic devices.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 5","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adom.202402444","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143397066","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 study explores how the phase and magnitude of transmission through the nanopatterned layer of the metasurface TARC are impacted by these parameters and subsequently influence the resulting contrast in emissivity between the low- and high-temperature states. When these parameters are optimized, the emissive contrast (8–13 µm) is predicted to be as high as 0.725 and 0.607 respectively for the undoped and doped TARCs. Additionally, this study investigates the use of alumina (Al2O3), a dielectric spacer with significant mechanical stability, and experimentally demonstrate the realization of metasurface TARCs with notably high emissive contrast. The findings describe the fundamental limits of emissivity contrast that can be achieved with a metasurface TARC composed of a WxV1-xO2 layer deposited atop an Al2O3 coated aluminum ground plane. Ultimately, the study provides a deeper understanding of the underlying physics of TARCs and demonstrates that metasurface engineering can be used to achieve enhanced control in tuning their emissive contrast.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 5","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143397032","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}

Currently, the main design principle depends on the amplitude modulation for the incident beam, which requires high-loss material and multiplex resonances, with fabrication duplication and severe crosstalk. Herein, two kinds of visible broadband metasurface absorbers are proposed based on the phase-modulation principle. The first is composed of a staggered Al trapezoidal array on the SiO2/Al substrate, where adjacent units have a phase difference of π for the y-polarized beam to generate the destructive interference, leading to a high average measured absorptivity of 73.37% for the whole visible band. On the contrary, this absorber reflects the x-polarized beam with a reflectivity of 51.65%. To achieve polarization-independent absorption, a 3×3 supercell metasurface is proposed, consisting of two groups of quasi-trapezoidal interlaced arrangements in the x- and y-directions separately. The measured spectra exhibit perfect polarization independence and excellent absorption (84.13%). Besides, both have angle robustness within 60° and refractive index robustness within 1.49. In theory, the influence of diffraction on the absorption effect is emphasized systematically. This research proposes a novel strategy to achieve broadband absorption, which can serve as a platform for polarizers, solar batteries, etc.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 7","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143554587","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}

All inorganic metal halide double perovskites possess the advantages of facile preparation procedures and high thermal stability, which also provide suitable doping sites to regulate the emission behavior and highlight the potential for serving as multi-modal fluorescence anti-counterfeiting materials. Herein, a series of Sb3+, Er3+, and Yb3+ solely or codoped Cs2NaLuCl6 are successfully prepared, and the optical properties are dependent on the doping ratio of Sb3+ and lanthanide ions (Ln3+). Notably, due to the participation of energy-transfer and cross-relaxation processes, the tri-doped Cs2NaLuCl6 (0.3%Sb3+-20%Er3+-50%Yb3+-Cs2NaLuCl6) shows luminescence responses to the excitation sources with different photon energies, which is employed to construct anti-counterfeiting fluorescence patterns by combining the Sb3+, Er3+, and Yb3+ solely or codoped Cs2NaLuCl6. Besides the multi-modal luminescence behavior, NIR emission from Er3+ and Yb3+ can be used in the night-vision device. Remarkably, the 20%Er3+-doped Cs2NaLuCl6 shows an excellent light yield of 30767 photons MeV−1 and low limit of detection (LoD) of 108 nGy s−1, highlighting the potential in X-ray imaging. This work provides a rational route to design multi-functional materials that can be used in anti-counterfeiting, night vision, and X-ray imaging.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 9","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143688806","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, creating efficient RTP materials that possess multiple optical properties remains a challenge. Herein, a novel approach is developed to in situ form carbon quantum dots (C-dots) embedded in boron nitride carbide oxide (B-N-C-O) matrices by introducing nitrogen, phosphorus, and boron dopants into C-dots (P/B/N doped C-dots), enabling dual RTP emissions and time-dependent afterglow. P/B/N doped C-dots are synthesized by a vacuum-assisted gradient heating approach using ethylenediamine, phosphoric acid, and boric acid as precursors with a yield of 20 g per batch. The introduction of P/B/N dopants provided multiple triplet states, which enable the C-dots to have dual RTP emissions and, a long phosphorescent lifetime ranging from 0.98 to 1.30 s. The in situ formation of matrices surrounding the C-dots enables ultrahigh quantum yield of up to 50%, surpassing the most recently reported RTP C-dots. To demonstrate the potential applications of the RTP C-dots, they are used as anti-counterfeiting ink and phosphorescent dyes for security codes and phosphorescent polyester yarn, showing their suitability for high-level security applications. This work provides an effective route for large-scale synthesis of highly efficient RTP materials and preparation of high-performance optical devices.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 4","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143113343","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}

These features alongside the tunability of their solid-state packing arrangement via chemical functionalization make this material class an excellent candidate for exciton-polariton lasing at room temperature. Polariton lasing is well understood in III–V semiconductors at cryogenic temperatures, however, the search for emitter materials for robust and versatile room-temperature applications is ongoing. While, e.g., perovskites and several organic materials are identified to support polariton lasing, many of these materials lack tunability and long-term stability under ambient conditions. Here, optical microcavities are fabricated using a strongly enwrapped PBI chromophore with prevailing monomer-like absorption and emission properties in the solid state. Voluminous bay-substituents prevent π-π-stacking induced PLQY-quenching, thereby enabling polariton lasing at room temperature. Additionally, photonic confinement in single hemispheric resonators is demonstrated leading to localized polaritonic modes with discrete energies, as well as optical lattices revealing distinct polaritonic band-structures. Due to the possibility of tunable properties by the precise control of the solid-state packing arrangement of PBI emitters, the results pave the way for polarization-dependent light-matter coupling, including topological photonic effects within oriented crystalline thin-film microcavity structures.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 7","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adom.202402617","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143554921","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}
