Here, we present a doping strategy using fourRE ions (La3+, Nd3+, Gd3+, and Er3+) doped into FAPbI3 PNCs under mild conditions(50 °C) in an ambient atmosphere. Density functional theory calculationswere performed to rationalize the RE incorporation by evaluating theformation energy of possible dopant configurations within the FAPbI3 lattice. The results demonstrated that RE ions were successfullyintroduced into interstitial sites in the FAPbI3 latticeunder mild conditions. RE-doped FAPbI3 PNCs were demonstratedto preserve the structure of α-FAPbI3 PNCs, whileimproving the optical properties in colloidal and thin-film samples,delivering an enhanced power conversion efficiency of 18.65% in photovoltaicperformance together with improved stability relative to pristinePNCs.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":"26 40","pages":"13948–13954"},"PeriodicalIF":9.1,"publicationDate":"2026-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149173860","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here,we reveal that Li corrosion is spatially heterogeneous: five timesmore capacity is lost at the edge overhang area of the current collectorthan at the center in the coin cell form factor. To address this,we developed a selected-area insulating layer (SAIL) that preventsLi plating in the overhang, yielding a 94% reduction in corrosion-inducedcapacity loss. Electron microscopy and titration gas chromatographywere employed to visualize the morphological heterogeneity and quantifythe disconnected Li loss at the center versus the overhang. Preventingdendritic Li plating in the overhang of the current collector cantherefore substantially mitigate calendar aging-induced capacity loss.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":"26 40","pages":"13759–13766"},"PeriodicalIF":9.1,"publicationDate":"2026-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149173526","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, experimentally probing and sensing the evolution of vdW interaction between 2D layers remains challenging due to its extreme weakness, very short range, and the difficulty of keeping two atomic layers perfectly parallel while finely adjusting the interaction. Here, we demonstrate an optical strategy to indirectly probe vdW interactions by exploiting induced anisotropy in MoS2/NbIrTe4 heterostructures. We construct heterostructures using isotropic MoS2 and anisotropic NbIrTe4 to ensure perfect parallelism. We modulate and probe the vdW interaction by varying the NbIrTe4 thickness and monitor the vdW-interaction-induced anisotropy in MoS2. We find such induced anisotropy to strongly depend on the NbIrTe4 thickness and clearly observe its fast-decaying nature. This work provides a simple, noncontact approach for indirectly probing interlayer vdW interactions.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":"50 1","pages":""},"PeriodicalIF":10.8,"publicationDate":"2026-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149209325","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we present a novel 2D colloidal heterostructuredesign, combining a CdSe core nanoplatelet, a CdS crown, and a CdZnSshell, to achieve bright bicolor emission in the solid state (green/red)emission with tunable intensity ratios controlled by excitation power(either optical or electrical). Integration of these nanoplateletsinto a dielectric cavity further narrows the emission linewidth tosub-2 nm while enhancing the photoluminescence intensity by up to200 times, meeting the Rec. 2020 color purity targets.
