Self-assembly of [2×2] grids and a hexagon using bis(dipyrrin)s

Li Ma、Brian O. Patrick、David Dolphin2010-11-10Chemical Communications

Neutral Zn(II) [2×2] grids (M(4)L(4)) and a hexagon structure (M(6)L(6)) were, for the first time, synthesized using bis(dipyrrin)s and confirmed by X-ray diffraction analysis. The channel structures in the solid state result from several intermolecular noncovalent interactions.

Magnetic plasmon resonance: Underlying route to plasmonic electromagnetically induced transparency in metamaterials

Yuehui Lu、Hua Xu、J. Y. Rhee 等 6 位作者2010-11-10Physical Review B

Surface plasmon polaritons, as a surface electromagnetic wave, have plenty of features in the near-field zone. We find that not only localized SSPs but also magnetic plasmon resonance play a vital role in plasmonic electromagnetically induced transparency (EIT). Their interaction is investigated in detail by analyzing…

Efficient optimization method for the light extraction from periodically modulated LEDs using reciprocity

O. T. A. Janssen、Arthur J. H. Wachters、H. P. Urbach2010-11-10Optics Express

The incoherent emission of periodically structured Light Emitting Diodes (LEDs) can be computed at relatively low computational cost by applying the reciprocity method. We show that by another application of the reciprocity principle, the structure of the LED can be optimized to obtain a high emission. We demonstrate…
