| 1 | Mechanosynthesis of polymer-stabilized lead bromide perovskites:Insight into the formation and phase conversion of nanoparticles显示文摘The application of polymers to replace oleylamine(OLA)and oleic acid(OA)as ligands for perovskite nanocrystals is an effective strategy to improve their stability and durability especially for the solution-based processing.Herein,we report a mechanosynthesis of lead bromide perovskite nanoparticles(NPs)stabilized by partially hydrolyzed poly(methyl methacrylate)(h-PMMA)and highmolecular-weight highly-branched poly(ethylenimine)(PEI-25K).The as-synthesized NP solutions exhibited green emission centered at 516 nm,possessing a narrow full-width at half-maximum of 17 nm and as high photoluminescence quantum yield(PL QY)as 85%,while showing excellent durability and resistance to polar solvents,e.g.,methanol.The colloids of polymer-stabilized NPs were directly processable toform stable and strongly-emitting thin films and solids,making them attractive as gain media.Furthermore,the roles of h-PMMA and PEI-25K in the grinding process were studied in depth.The h-PMMA can form micelles in the grinding solvent of dichloromethane to act as size-regulating templates for the growth of NPs.The PEI-25K with large amounts of amino groups induced significant enrichment of PbBr_(2)in the reaction mixture,which in turn caused the formation of CsPb_(2)Br_(5)-mPbBr_(2)and CsPbBr_(3)-Cs_(4)PbBr_(6)-nCsBr NPs.The presence of CsPbBr_(3)-Cs_(4)PbBr_(6)-nCsBr NPs was responsible for the high PL QY,as the Cs_(4)PbBr_(6)phase with a wide energy bandgap can passivate the surface defects of the CsPbBr_(3)phase.This work describes a direct and facile mechanosynthesis of polymer-coordinated perovskite NPs and promotes in-depth understanding of the formation and phase conversion for perovskite NPs in the grinding process. | Guocan Jiang Onur Erdem Rene Hubner Maximilian Georgi Wei Wei Xuelin Fan Jin Wang Hilmi Volkan Demir Nikolai Gaponik | 2021 | Nano Research2021，14，4： | 0 |
| 2 | Ultra-dense planar metallic nanowire arrays with extremely large anisotropic optical and magnetic properties显示文摘为对晶片尺寸可伸缩的极端稠密的平面金属性的 nanowire 数组的生产的一个 nanofabrication 方法被介绍。方法基于一个有效模板免职过程在仅仅二步与极端整齐种多样的金属性的 nanowire 数组。首先, III-V 半导体底层被一根低精力的离子横梁在提高的温度照耀,形成由一个反向的取向附生过程由于的一个高度订的 nanogroove 模式表面空缺自己组装。第二,多样的金属性的 nanowire 穿(Au, Fe, Ni,公司, FeAl 合金) 被免职在一个看一眼的发生角度在这些 III-V 模板上制作。这个方法允许有频率的数组击倒到 45 nm 的金属性的 nanowire 的制造可伸缩直到晶片尺寸制造。作为典型高贵、磁性的金属,这里生产的 Au 和 Fe nanowire 数组展出了大各向异性光并且磁性分别地。Au nanowire 数组的局部性的表面电浆子回声(LSPR ) 的刺激导致了高电场改进,它被用来在散布的提高表面的拉曼(重量的单位) 检测酞毒(CoPc ) 。而且, Fe nanowire 数组显示出一架很高的在里面飞机约 412 mT 的磁性的 anisotropy,它磁性的 anisotropy 还回答的最大的在里面飞机可以被报导那完全在一部薄电影的飞机以内经由形状 anisotropy 被导致。 | Qi Jia Xin Ou Manuel Langer Benjamin Schreiber Jorg Grenzer Pablo F.
