These systems are attractive as they enable the thermal management of PV cells to maintain optimal operating temperatures and maximize the overall solar energy conversion. Despite their advantages, HPT systems have been limited to storing solar energy in the form of heat or simple water/space heating, thus restricting the broader application scope of HPT systems, particularly in regions with abundant solar energy. Here, we introduce a device that expands the scope of HPT applications by realizing a hybrid PV/ water desalination system, achieved through the integration of a Fano-resonant optical coating (FROC) onto a silicon substrate, which is turned superwicking via femtosecond laser surface patterning. This configuration allows a single-junction amorphous silicon solar cell to operate under higher solar concentrations with much less heat conversion, achieving a temperature reduction of 101 °C and an efficiency improvement of 335.7% compared to a standalone photovoltaic system under the solar concentration of 5. At the same time, the interfacial water desalination achieves a 2 ({kg}{m}^{-2}{h}^{-1}) high evaporation rate. Over a 12-hour cycle, our HPT system showed a consistent performance, demonstrating a combined solar conversion efficiency of 79.6%. The demonstrated superwicking-FROC will pave the way for widespread adoption of HPT systems particularly in sunny coastal regions.","PeriodicalId":18069,"journal":{"name":"Light-Science & Applications","volume":"17 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143841467","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This method continuously and autonomously learns from the system, effectively accumulating experiential knowledge for calibration strategies and demonstrating superior adaptability compared to traditional methods. In systems based on dispersion compensating fiber, micro-ring resonator array, and Mach-Zehnder interferometer array that use multi-wavelength optical carriers as the light source, the DRC method enables the completion of the corresponding signal processing functions within 21 iterations.

Here, we disclose a supramolecular approach to construct a hollow-spherical supra-(carbon dots) (HS-Pt-CDs) via ultrasound-assisted J-type assembly of Pt(IV)-coordinated carbon dots (Pt-CDs). The peculiar assembling behaviors arise from the steric hindrance and lattice distortion in the bowl-like Pt-CDs caused by the coordination of Pt(IV) atoms among the sp2 domains, which result in around 240 nm red-shifted absorption bands and promoting charge separation in the NIR region due to strong inter-molecular charge transfer (CT) in HS-Pt-CDs. The results reveal that HS-Pt-CDs exhibit excellent NIR light-activated photocatalytic capacities, involving the release of Pt(II) species, the generation of hydroxyl radicals, and acidification under 690 nm laser irradiation. Combined with the effective cellular uptake and tumor accumulation, HS-Pt-CDs can efficiently trigger cancer cell pyroptosis under 690 nm laser irradiation, resulting in the destruction of the primary tumor and effectively induction of strong immunogenic cell death (ICD), thereby evoking anti-tumor immune responses to suppress distant tumor and prevent cancer metastasis. Taken these merits, an important perspective of Pt(IV)-contained supra-CDs with outstanding NIR-triggered photocatalytic behaviors can be of great significance toward precision tumor phototherapy.","PeriodicalId":18069,"journal":{"name":"Light-Science & Applications","volume":"24 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143831688","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The combination of optical encoding and computational decoding offers enhanced imaging and sensing capabilities with diverse applications in biomedicine, astronomy, agriculture, etc. With the great advance of artificial intelligence in the last decade, deep learning has further boosted computational optics with higher precision and efficiency. Recently, there developed an end-to-end joint optimization technique that digitally twins optical encoding to neural network layers, and then facilitates simultaneous optimization with the decoding process. This framework offers effective performance enhancement over conventional techniques. However, the reverse physical twinning from optimized encoding parameters to practical modulation elements faces a serious challenge, due to the discrepant gap in such as bit depth, numerical range, and stability. In this regard, this review explores various optical modulation elements across spatial, phase, and spectral dimensions in the digital twin model for joint encoding-decoding optimization. Our analysis offers constructive guidance for finding the most appropriate modulation element in diverse imaging and sensing tasks concerning various requirements of precision, speed, and robustness.

Recent advances in the artificial structuring of scintillators offer new opportunities for improving the energy resolution of scintillator-based X-ray detectors. Here, we present a three-bin energy-resolved X-ray imaging framework based on a three-layer multicolor scintillator used in conjunction with a physics-aware image postprocessing algorithm. The multicolor scintillator is able to preserve X-ray energy information through the combination of emission wavelength multiplexing and energy-dependent isolation of X-ray absorption in specific layers. The dominant emission color and the radius of the spot measured by the detector are used to infer the incident X-ray energy based on prior knowledge of the energy-dependent absorption profiles of the scintillator stack. Through ab initio Monte Carlo simulations, we show that our approach can achieve an energy reconstruction accuracy of 49.7%, which is only 2% below the maximum accuracy achievable with realistic scintillators. We apply our framework to medical phantom imaging simulations where we demonstrate that it can effectively differentiate iodine and gadolinium-based contrast agents from bone, muscle, and soft tissue.","PeriodicalId":18069,"journal":{"name":"Light-Science & Applications","volume":"39 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143819090","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we demonstrate a non-reciprocal magneto-optic response by integrating multilayer 2D CuCrP2S6 (CCPS) onto silicon microring resonators (MRRs). Under an applied magnetic field, the CCPS intralayer ferromagnetic ordering, characterized by easy-plane magneto-crystalline anisotropy, induces asymmetrical modal responses in the clockwise (CW) and counterclockwise (CCW) light propagation directions. The proposed configuration achieves a low insertion loss ranging from 0.15 dB to 1.8 dB and a high isolation ratio of 28 dB at 1550 nm. Notably, it exhibits a significant resonance wavelength splitting of 0.4 nm between the counter propagation directions, supporting a 50 GHz optical bandwidth. Operating directly in the transverse electric (TE) mode, it aligns with the main polarization used in silicon photonics circuits, eliminating the need for additional polarization management. The device is ultra-compact, with a 2D flake interaction length ranging from 22 µm to 55 µm and a thickness between 39 nm and 62 nm. Its operation range covers the entire C-band with a bandwidth of up to 100 nm.

The tBuCz-m-CF3 and tBuCz-p-CF3 complexes are designed to enhance steric encumbrance and minimize exciton accumulation. These innovations lead to exceptional photoluminescence quantum yields (PLQY) of 98% and an impressive decay rate constant of 7.97 × 105 s−1 in doped thin films. The Ph-OLEDs emit blue light with a peak wavelength of 485 nm and CIE coordinates of (0.175, 0.446), exhibiting a peak external quantum efficiencies (EQE) of 31.62% and brightness up to 214,255 cd m−2. Notably, they shown minimal efficiency roll-off, retaining an EQE of 27.76% at 10,000 cd m−2, and 20.58% at 100,000 cd m−2. These consistent performances across various brightness levels represent a significant milestone for blue Ph-OLED technology. The devices also exhibit impressive stability, with an operational lifetime (LT50, the time taken for luminance to decrease by 50%) reaching 1237 h at 1000 cd m−2, setting new benchmarks for blue Ph-OLEDs.
