However, their performance presently lags far behind that of state-of-the-art white organic LEDs owing to a lack of efficient white quantum dot emitters. Creating self-trapped excitons in semiconductor quantum dots is a promising approach to producing broadband white emission. However, such emitters generally suffer from poor charge transport and structural instability. Here we accomplish controllable synthesis of core/shell structured ZnSe/ZnS quantum dots with efficient white emission through combining a sharp excitonic blue emission with a broadband yellow self-trapped exciton emission owing to local lattice softening of ZnSe cores by heterovalent doping with halogen ions. We reveal that the self-trapped excitons confined in the surrounding ZnSe covalent-bond matrix can generate strong and stable yellow emission with minimal reduction of the excitonic blue emission and charge transport capability of ZnSe. On the basis of this approach, we demonstrate highly efficient, heavy-metal-free WQLEDs with a maximum external quantum efficiency up to 15% (average 10.5 ± 2.6%), a luminance of over 26,000 cd m−2 as well as exceptional device operational lifetime with T50 exceeding 2,500 h at an initial luminance of 100 cd m−2.","PeriodicalId":18926,"journal":{"name":"Nature Photonics","volume":"102 1","pages":""},"PeriodicalIF":35.0,"publicationDate":"2025-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144640413","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 demonstrate the growth of coherent perovskite heterojunctions and quantum wells made of mixed-dimensional perovskites using a solution process. By exploiting the solubility difference of methylammonium (MA+) and 4-(aminomethyl)piperidinium (4AMP2+), we assemble layered perovskites with different layer numbers. The resulting 4AMP-MAn–1PbnI3n+1 materials each with different layer numbers or bandgaps form quantum wells. Heterojunctions and quantum wells made of 4AMP-MA2Pb3I10 (n = 3) and 4AMP-MAPb2I7 (n = 2) with various barrier thickness are tailored by the solution temperature profile during crystal growth. Multiple quantum wells have been formed by cycling temperature profiles. The planar heterojunction and quantum wells have lattice matching without interfacial defects, and exhibit strong thermal stability. Type I band alignment at the n = 2/n = 3 heterojunction is confirmed by both computation and optical studies.

Conversely, lasers with shorter (a few femtoseconds) pulse durations and lower peak powers enable the generation of isolated attosecond light pulses to study nature with unparalleled temporal resolution. Here we report an enhanced optical parametric chirped pulse amplifier system that produces light pulses with a peak power of about 100 TW and a pulse duration as short as 4.3 fs with full waveform control. Coherent field synthesis generates a broadband spectrum, spanning from the visible to the near infrared, through three cascaded amplification stages, each housing two optical parametric amplifiers that sequentially boost complementary spectral regions. The resulting light transients are waveform-stabilized to <300 mrad and focused to an intensity of 1021 W cm−2 and exhibit an outstanding high dynamic range in temporal contrast. Together, these characteristics render the system well suited for demanding relativistic laser–plasma experiments. Utilizing temporal super-resolution, the pulses are shortened to sub-4-fs duration.

Recent advances in quasi-continuous-wave stimulated Brillouin scattering have substantially reduced the required laser power. However, the pixel dwell time remains limited to 20 ms, and further reductions without compromising resolution, precision or specificity are challenging. Here we address this limitation by developing a frequency-doubled pulsed fibre laser system operating at 780 nm, delivering a peak power of 267 W. To mitigate the high-intensity noise intrinsic to amplified fibre lasers, we implement a high-performance noise cancellation system based on auto-balanced detection. As a result, we achieve a pixel dwell time as short as 200 µs for full spectral acquisition, which is two orders of magnitude faster than previous stimulated Brillouin scattering implementations, and maintain an average power of 30 mW. We demonstrate high-speed, high-specificity and high-sensitivity Brillouin imaging of live single cells, organoids, zebrafish larvae and ovarian follicles with subcellular details. Furthermore, we capture the in vivo biomechanical dynamics of rapid cell divisions during the early embryo development of Caenorhabditis elegans in a living worm.","PeriodicalId":18926,"journal":{"name":"Nature Photonics","volume":"10 1","pages":""},"PeriodicalIF":35.0,"publicationDate":"2025-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144593854","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, this technology is still severely limited by the low efficiency of blue OLEDs. Developing high-performance blue OLEDs is a major challenge, and emitters are critical for overcoming this issue. Here we design phosphorescent platinum(ii) complexes with a locally excited-dominated character and a rigid three-dimensional geometry to suppress intermolecular interactions, enabling robust deep-blue devices. Bottom-emitting OLEDs emit at 464 nm with a full-width at half-maximum of 17.1 nm and high external quantum efficiencies of 30.8%, 26.4% and 23.2% at 1,000 cd m−2, 5,000 cd m−2 and 10,000 cd m−2, respectively. Top-emitting devices achieve enhanced colour purity (full-width at half-maximum of 13.1 nm, CIEy = 0.062), a low running voltage (3.9 V at 1,000 cd m−2) and a maximum blue index of 468 cd A−1 CIEy−1.

These structures often have permanent working spectral ranges and optical properties that are fixed during fabrication. Quantum materials, with their correlated and intertwined degrees of freedom, offer a promising avenue for dynamically controlling photonic devices without altering their physical structure. Here we fabricate photonic crystal slabs from CrSBr, a van der Waals antiferromagnetic semiconductor, and demonstrate in situ control over their optical properties. Leveraging the combination of the exceptionally large refractive index of CrSBr near its excitonic resonances and its tunability via external fields, we achieve precise manipulation of photonic modes at near-visible and infrared wavelengths, showcasing a new paradigm for nanophotonic device design. The resulting guided resonances of the photonic crystal are tightly packed in the spectrum with very small mode volumes, are highly tunable via external magnetic fields and exhibit high Q factors exceeding 1,200. These resonances self-hybridize with the excitonic degrees of freedom, resulting in intrinsic strong light–matter coupling. Our findings underscore the potential of quantum materials for developing in situ tunable photonic elements and cavities.","PeriodicalId":18926,"journal":{"name":"Nature Photonics","volume":"11 1","pages":""},"PeriodicalIF":35.0,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144578125","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}
