Yet, the inherent proton exchange between conventional capping molecules introduces an unstable surface, consistently leading to diminished performance. Here, a sole chelating ligand capping method is proposed for synthesizing anisotropic CsPbBr3 NPLs, which serve as the model system due to their significant appeal for blue light-emitting applications. A chelating ligand (CTE) is designed via a straightforward solution-based amidation reaction between oleylamine and ethylenediaminetetraacetic acid; acting as the sole surfactant, CTE strongly coordinates with the Pb2+ precursor, directly facilitating the formation of (PbBr6)4– octahedrons and circumventing the protonation/deprotonation process. This strategy allows further post-treatment with 4-phenylbutylammonium bromide while maintaining NPLs’ emission characteristics and anisotropic morphology. As a result, pure blue-emitting CsPbBr3 NPLs with a PLQY of 97% can be achieved, and their photophysical and structural characteristics remain stable over 30 days under ambient conditions.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"7 1","pages":"59–67 59–67"},"PeriodicalIF":9.6,"publicationDate":"2024-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/epdf/10.1021/acsmaterialslett.4c02269","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143091866","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, mainstream transition-metal ions (Cr3+, Mn4+, etc.) and lanthanides (Nd3+, Yb3+, etc.) activated NIR phosphors suffer from the low absorption efficiency due to the spin-forbidden d-d or f-f transitions. Herein, we present a robust (Ba,Sr)Al3Si3O4N5:Sm2+ NIR phosphor that exhibits a broad-band peaking at 758 nm with high absorption efficiency stemming from the spin-allowed 4f-5d transition. The lowest excited level in 4f6 (5D0) is equivalent to the 4f55d1 of Sm2+, as evidenced by the temperature-dependent (5–300 K) emission spectra. The emission peaks of Sm2+ in these oxynitride phosphors can be tuned between 742 and 789 nm by simply changing the doping concentration. The optimized NIR phosphor exhibits excellent thermal and chemical stability, making it highly promising in encryption and nondestructive inspection. This work provides a pathway to exploring highly efficient and stable broadband Sm2+-doped NIR phosphors for optoelectronic applications.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"7 1","pages":"68–75 68–75"},"PeriodicalIF":9.6,"publicationDate":"2024-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143091867","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we analyze the effects of electrode erosion by examining alumina spheres exposed to the plasma using electron microscopy for detailed characterization. Our findings show that electrode erosion leads to the deposition of microscopic particles on the materials inside the plasma reactor. Whereas the operating parameters influence the properties of these particles, their formation and deposition is persistent. These electrode particles are an evident source of contamination and may lead to impurities in synthesized materials or altered plasma discharges after long-term operation. Our study highlights the importance of acknowledging the presence and potential impact of these particles for various DBD plasma applications and calls for greater awareness in the scientific community regarding this source of contamination that has been overlooked so far.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"7 1","pages":"52–58 52–58"},"PeriodicalIF":9.6,"publicationDate":"2024-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143091647","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we unravel the degradation mechanisms of the most promising and widely used HTM, di-[4-(N,N-di-p-tolyl-amino)-phenyl]cyclohexane (TAPC). A luminescent defect is discovered in TAPC during degradation in blue OLEDs, which is induced by a two-step electron-induced process. To suppress this degradation, we propose a negative-charge management strategy by introducing a strong electron-withdrawing material, fullerene, at the TAPC interface. This strategy is proven effective in blue phosphorescent OLEDs, resulting in not only a 10-fold enhancement in operational lifetime but also a significant suppression in efficiency roll-off at high brightness over 30 000 cd m–2. Our findings offer a feasible solution to improve the operational stability of blue OLEDs in which the degradation of HTM plays a role, potentially accelerating the commercialization of high-efficiency long-lasting OLED displays.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"7 1","pages":"32–40 32–40"},"PeriodicalIF":9.6,"publicationDate":"2024-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/epdf/10.1021/acsmaterialslett.4c01758","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143091644","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite progress in understanding this phenomenon, atomic-scale mechanisms, particularly under photoexcitation, remain complex and are partially understood. Here, we introduce a new computational framework combining constrained Density Functional Theory (CDFT) with machine learning potential (MLP) to explore Peierls stress and dislocation dynamics in zinc sulfide (ZnS) under both ground and excited states. Our results reveal that photoexcitation significantly increases Peierls stress by reducing strain concentration at the dislocation core, contributing to the transition from ductility to brittleness under light exposure. Importantly, this enhancement occurs without substantial changes in the dislocation core structure. These insights provide an understanding of the atomic-scale mechanisms behind photoplasticity in ZnS, demonstrating that integrating CDFT with MLP is a highly accurate and efficient approach to study complex material behaviors under photoexcitation.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"7 1","pages":"46–51 46–51"},"PeriodicalIF":9.6,"publicationDate":"2024-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143091638","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We find the unusual preceding growth of electron signal in 0–0.35 eV compared with that in 0.35–0.70 eV and 0.70–1.05 eV during the absorption of UV (3.10 eV) pulses, unambiguously suggesting the occurrence of impact ionization.

Taking into account the electron–phonon scatterings during the electron thermalization, the CM value is calculated to be 2.0 and 1.4 under UV and IR excitation, respectively.
