Bulky Surface Ligands Promote Surface Reactivities of [Ag141X12(S-Adm)40]3+ (X=Cl, Br, I) Nanoclusters: Models for Multiple-Twinned Nanoparticles
Ren, Liting; Yuan, Peng; Su, Haifeng; Malola, Sami; Lin, Shuichao; Tang, Zichao; Teo, Boon K.; Häkkinen, Hannu; Zheng, Lansun; Zheng, Nanfeng (American Chemical Society, 2017)Surface ligands play important roles in controlling the size and shape of metal nanoparticles and their surface properties. In this work, we demonstrate that the use of bulky thiolate ligands, along with halides, as the ... -
Surface Coordination of Multiple Ligands Endows N‐Heterocyclic Carbene‐Stabilized Gold Nanoclusters with High Robustness and Surface Reactivity
Shen, Hui; Xu, Zhen; Hazer, Maryam Sabooni Asre; Wu, Qingyuan; Peng, Jiang; Qin, Ruixuan; Malola, Sami; Teo, Boon K.; Häkkinen, Hannu; Zheng, Nanfeng (Wiley-VCH Verlag, 2021)Deciphering the molecular pictures of the multi-component and non-periodic organic-inorganic interlayer is a grand technical challenge. Here we show that the atomic arrangement of hybrid surface ligands on metal nanoparticles ... -
Graphene plasmonics for surface-enhanced infrared spectroscopy
Plyushch, Alexander (2020)The work, presented in this thesis, focuses on studying graphene as a signal enhancing material for spectroscopic applications. Among many outstanding characteristics of graphene, it also exhibits attractive plasmonic ... -
Strong coupling between surface plasmon polaritons and molecules : Lindblad equation approach
Asikainen, Aili (2016)Pintaplasmonipolaritonit (SPP) ovat metallin ja dielektrisen aineen, esim. ilma, rajapintaan syntyviä sähkömagneettisia aaltoja. Tämä työ käsittelee SPP:en ja molekyylien välistä vuorovaikutusta vahvan kytkennän rajalla. ...
