However, their development is hindered by inefficient vertical phase transformation within thick, multi-layered films, which results in incomplete infiltration, premature surface nucleation and residual stress. Here we report a fluid motion crystallization strategy employing a co-solvent system of ionic liquid methylammonium propionate and butyronitrile. The butyronitrile reduces the fluid motion resistance and disperses PbI2 aggregates with optimized solvation structure, enabling rapid and deep infiltration of the perovskite precursor. This promotes a bottom-up, ordered phase transition before surface nucleation, effectively suppressing defect formation. The subsequent growth of a dense, interconnected perovskite nanocrystal network featuring an island-like surface morphology strengthens the interfacial contact with the carbon electrode. This intimate contact enhances the carrier transport and minimizes the recombination losses. Finally, air-processed, fully screen-printed perovskite solar cells yield a power conversion efficiency of 22.41% (certified 21.86%). Devices retain over 90.5% of their initial power conversion efficiency after 2,000 h under International Summit on Organic Photovoltaic Stability light-soaking-1 (ISOS-L-1) accelerated ageing conditions and show no degradation after 900 h of operation at 85 °C with 50% ± 10% relative humidity (ISOS-L-3 protocol).","PeriodicalId":18926,"journal":{"name":"Nature Photonics","volume":"72 1","pages":""},"PeriodicalIF":35.0,"publicationDate":"2026-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148853501","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, material limitations and integration constraints have restricted the accessible wavelengths and operation bandwidths of current mid-infrared lasers. Here we address these challenges by developing a nonlinear integrated photonic device that converts a fixed-wavelength near-infrared pump laser into broadly tunable mid-infrared light. Our device, an optical parametric oscillator integrated on thin-film lithium niobate, generates 22 THz of multi-milliwatt, voltage-tunable radiation from 2.7 to 3.4 μm, a region typically difficult to access but vital for environmental, chemical and biological sensing. By introducing an on-chip-tunable parametric oscillator architecture taking advantage of the Vernier effect, we obtain electrical control of the emission wavelengths from coarse, multi-terahertz scales down to continuous, sub-100-GHz mode-hop-free tuning ranges. This work establishes a robust platform for a new class of compact, widely tunable mid-infrared sources with potential for future scaling.","PeriodicalId":18926,"journal":{"name":"Nature Photonics","volume":"11 1","pages":""},"PeriodicalIF":35.0,"publicationDate":"2026-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148853500","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we introduce an in situ dry repair and passivation (IDRP) technique that effectively eliminates plasma-induced sidewall damage, unlocking the full potential of micro-scale devices. This approach not only substantially overcomes the size-related efficiency degradation but also enables a reversed size effect, where efficiency increases as dimensions shrink, even down to 1.6 μm devices. The IDRP-treated devices also exhibit substantially improved manufacturing yield and electrostatic discharge robustness. The IDRP strategy proves universally effective across the nitride-based spectrum, leading to record-high peak external quantum efficiencies of 64.7% and 55.1% for 2 μm blue and green InGaN micro-LEDs, respectively. These unprecedented performance metrics enable high-performance pixels, demonstrated here in a nitride microdisplay tailored for emerging augmented reality and virtual reality applications. As a fully integrated, semiconductor-standard dry process, IDRP provides a simple, rapid and powerful route to advance the industrialization of micro-LEDs, representing a transformative technology for large-scale display manufacturing. An in situ dry repair and passivation technique is developed to overcome plasma-induced sidewall damage in nitride-based micro-light-emitting diodes (micro-LEDs), leading to external quantum efficiencies of 64.7% and 55.1% for 2-μm-sized blue and green micro-LEDs, respectively.","PeriodicalId":18926,"journal":{"name":"Nature Photonics","volume":"20 9","pages":"1099-1106"},"PeriodicalIF":38.1,"publicationDate":"2026-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148769235","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The development of the laser wakefield accelerator (LWFA) shows great potential for an advanced all-optical electron source based on LWFA in UED applications. Here we experimentally demonstrated that an LWFA-based device with a miniaturized permanent magnet beamline can generate and manipulate electron beams suitable for UED. During beam transport, the LWFA electron beams with intrinsically short duration undergo temporal stretching owing to the energy spread and are subsequently compressed by the following double-bend achromat. The optimized double-bend achromat can make the beamline isochronous such that the arrival time jitter induced by the shot-to-shot energy fluctuation can be eliminated, and allow the advantage of the natural laser-beam synchronization for LWFAs to emerge. With the energy filtering, the beam energy spread can be reduced to 3% (full-width at half-maximum), while a sufficient amount of charge (11.9 fC) per bunch for diffraction is retained. Using a laser-driven terahertz deflector, the beam length and arrival time jitter measured at the sample location are approximately 49.6 fs (root mean square (r.m.s.)) and 4.7 fs (r.m.s.), respectively, resulting in a temporal resolution of ~49.8 fs. Comprehensive start-to-end simulations indicate the potential of reducing the bunch length to ~10 fs (r.m.s.) with a lower energy spread of around 1.6%. Clear single-shot and multi-shot diffraction patterns of single-crystalline gold samples are obtained, and the derived lattice constant agrees well with the actual value. Our proof-of-principle experiments open the door to the detection of ultrafast structural dynamics using MeV LWFA beams, and pave the way for UED applications with sub-10 fs temporal resolution. Researchers demonstrate that a laser wakefield accelerator-based device with a miniaturized permanent magnet beamline can generate and manipulate electron beams suitable for ultrafast electron diffraction.","PeriodicalId":18926,"journal":{"name":"Nature Photonics","volume":"20 9","pages":"1056-1061"},"PeriodicalIF":38.1,"publicationDate":"2026-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148769171","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, a key challenge for semiconductor photon-counting computed tomography detectors is that existing response speeds are insufficient to count high-flux X-ray photons at a rate of 3 × 106–1 × 108 photons per second per square millimetre (s−1 mm−2) in common computed tomography scanning. Here we report a combination of edge-on device configuration and chloride alloying to increase the response speed of perovskite photon-counting detectors. The edge-on configuration shortens the charge collection distance by 15 times while maintaining the X-ray absorption, reducing charge transit time by 225 times. Surprisingly, we find that free charges generated by nearly every incident X-ray photon encounter shallow traps in formamidinium lead bromide (FAPbBr3) crystal devices. Chloride alloying of FAPbBr3 crystals dramatically reduces shallow trap density, increasing detector response speed. The high electric field in the edge-on detectors enables complete extraction of charges even if they are trapped by shallow defects. The resulting perovskite detectors show a response time of 37 ns after deconvolution. The edge-on detectors with a pixel size of 200 × 200 µm2 can count 120-kVp X-ray photons, with a high flux of 2 × 108 photons s−1 mm−2, enabling the application of perovskite photon-counting detectors for photon-counting computed tomography and many other applications.

Compared with the widely used gas-cell comagnetometer systems, cold-atom systems offer access to much shorter distance scales and allow the implementation of optical quantum control techniques. However, to realize long spin coherence times with cold atoms, it is necessary to use diamagnetic atoms and overcome decoherence induced by light shifts. Here we demonstrate a cold-atom comagnetometer based on the nuclear spins of 171Yb (spin-1/2) and 173Yb (spin-5/2), jointly trapped in an optical lattice. Vector light shifts are suppressed by enforcing linear polarization of the lattice, whereas tensor shifts in 173Yb are suppressed via the use of a Schrödinger cat state. This enables simultaneous Ramsey interferometry on both isotopes with a spin coherence time of 60 s. We achieve a magnetic noise suppression factor exceeding 3 × 104, and determine the 171Yb–173Yb ratio of nuclear magnetic moments to be –0.726076(3) with a 4-ppm precision.
