| 1 | Hybrid plasmonic–dielectric metal-nanowire coupler for high-efficiency broadband nonlinear frequency conversion显示文摘Pursuing nanometer-scale nonlinear converters based on second harmonic generation(SHG)is a stimulating strategy for bio-sensing,on-chip optical circuits,and quantum information processing,but the light-conversion efficiency is still poor in such ultra-small dimensional nanostructures.Herein,we demonstrate a highly enhanced broadband frequency converter through a hybrid plasmonic–dielectric coupler,a ZnTe/ZnO single core–shell nanowire(NW)integrated with silver(Ag)nanoparticles(NPs).The NW dimension has been optimized to allow the engineering of dielectric resonances at both fundamental wave and second harmonic frequencies.Meanwhile,the localized surface plasmon resonances are excited in the regime between the Ag NPs and ZnTe/ZnO dielectric NW,as evidenced by plasmon-enhanced Raman scattering and resonant absorption.These two contributors remarkably enhance local fields and consequently support the strong broadband SHG outputs in this hybrid nanostructure by releasing stringent phase-matching conditions.The proposed nanoscale nonlinear optical converter enables the manipulation of nonlinear light–matter interactions toward the development of on-chip nanophotonic systems. | KUI-YING NIE SONG LUO FANG-FANG REN XUANHU CHEN SHULIN GU ZHANGHAI CHEN RONG ZHANG JIANDONG YE | 2022 | Photonics Research2022，10，10： | 1 |
| 2 | Lanthanocene Diolate Complexes: Synthesis, Structures and Catalytic Property for ε-Caprolactone Polymerization显示文摘Reaction of LnCl3 first with three equivalent of C5H5Na in THF,then with one equivalent of N-phenyldiethanolamine in THF-DME afforded complexes of{[(C_(5)H_(5))Ln(μ-OCH_(2)CH_(2))_(2)N(C_(6)H_(5))]4(μ_(4)-C_(l))}[Na(DME)_(4)](Ln=Sm(1),Yb(2)),being characterized by infrared spectra,elemental analyses and X-ray crystallography.They are ionic pair compounds.The anionic part is a cluster,which can be viewed as a cyclic tetramer with four(C5H5)Ln units bridged by four pairs of OR groups,forming a pinwheel structure.Both the complexes can catalyze the ring-opening polymerization ofε-caprolactone under mild conditions,and complex 1 is more active than complex 2.The polymerization accords with one order reaction kinetics for monomer concentration.The molecular weight increases with the yield increasing,and the molecular weight distribution is rather narrow(1.19 | Zhanghai Gu Li Li Qianwen Bao Fugen Yuan | 2015 | Chinese Journal of Chemistry2015，33，5： | 0 |
