  Hunting for the Active Sites of Surface-Enhanced Raman Scattering:  A New Strategy Based on Single Silver Particles

  摘要：

  Three major findings are reported here. First, a new technique based on lithographic modification with a scanning tunneling microscope (STM) has been developed for fabricating single Ag particles on atomically flat Au(111) surfaces. Second, surface-enhanced Raman scattering (SERS) from one isolated Ag particle has been observed and quantified for the first time. The enhancement factor due to one Ag particle of about 1 mu m diameter is on the order of 10(4). This factor includes contributions from all forms of chemical enhancement, which are smaller than 10(2). Finally strong evidence suggests the importance of clusters containing closely-spaced particles. Extra enhancement due to clusters of randomly distributed Ag particles is around 10(2). We believe that the extra enhancement is spatially localized near the gap sites between two particles in proximity. These gap sites form an important class of SERS-active sites.

  (EN) An electroluminescent device is provided incorporating an emissive layer comprising a processible polymer matrix such as poly(methylmethacrylate) and a chromophoric component such as an asymmetric stilbene or distyrylbenzene. The chromophoric component is blended with the polymer matrix or covalently attached thereto as a side chain and is selected to emit radiation in the region 400 nm to 500 nm when excited to luminesce.(FR) Dispositif électroluminescent comprenant une couche émissive comportant une matrice polymère transformable telle que poly(méthylméthacrylate) et un constituant chromophore tel qu'un distyrylbenzène ou stilbène asymétrique. On mélange le constituant chromophore à la matrice polymère, ou on le lie de manière covalente à celle-ci sous forme de chaîne latérale, et on le choisit de sorte qu'il émette un rayonnement dans le domaine compris entre 400 et 500 nm lorsqu'on l'excite pour le rendre luminescent.
