The varying amount of randomly distributed nanocube aggregates with different surface coverages in gradient manner due to changes in surface pressure allows for continuous control of the polarization sensitive absorption of the incoming light over a broad optical spectrum. Optical characterization under total internal reflection conditions combined with electromagnetic simulations reveal that the broadband light absorption depends on the relative orientation of the nanoparticles to the polarization of the incoming light. By using computer simulations, we found that the electric field vector of the s-polarized light interacts with the different types of silver nanocube aggregations to excite different plasmonic resonances. The s-polarization shows dramatic changes of the plasmonic resonances at different angles of incidence (shift of 64 nm per 10[degree] angle of incidence). With a low surface nanocube coverage (from 5% to 20%), we observed a polarization-selective high absorption of 80% (with an average 75%) of the incoming light over a broad optical range in the visible region from 400 nm to 700 nm. This large-area gradient material with location-dependent optical properties can be of particular interest for broadband light absorption, phase-sensitive sensors, and imaging.</style></abstract><electronic-resource-num><style face="normal" font="default" size="100%">10.1039/C4NR06430E</style></electronic-resource-num></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">König, Tobias</style></author><author><style face="normal" font="default" size="100%">Kodiyath, Rajesh</style></author><author><style face="normal" font="default" size="100%">Combs, Zachary A.</style></author><author><style face="normal" font="default" size="100%">Mahmoud, Mahmoud</style></author><author><style face="normal" font="default" size="100%">El‐Sayed, Mostafa A</style></author><author><style face="normal" font="default" size="100%">Tsukruk, Vladimir V.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Silver Nanocube Aggregates in Cylindrical Pores for Higher Refractive Index Plasmonic Sensing</style></title><secondary-title><style face="normal" font="default" size="100%">Particle &amp;

After embedding the rods, sacrificial nickel segments were selectively etched leaving behind strongly coupled segmented gold nanorods with gaps between rods below 40 nm and as small as 2 nm. Hyper-spectral imaging is utilized to measure Rayleigh scattering spectra from individual and coupled nanorod elements in contrast to common bulk measurements. This approach discerns the effects of not only changing segment and gap size but also the presence of characteristic defects on the plasmonic coupling between closely spaced nanorods. Polarized hyper-spectral measurements are conducted to provide direct observation of the anisotropic plasmonic resonance modes in individual and coupled nanorods, which are close to those predicted by computer simulations for nanorods with ideal shapes. Some common deviations from ideal shape such as non-flat facets and asymmetric tails are demonstrated to result in the appearance of characteristic plasmon resonances, which have not been considered before. The large-scale assembly of coupled noble nanostructures with fine control over geometry and high uniformity provides means to strongly tune the scattering, absorption, and near-field plasmonic properties through the geometric arrangement of precisely controlled nanorod segments.[on SciFinder (R)]</style></abstract><notes><style face="normal" font="default" size="100%">MEDLINE AN 2013463112(Journal; Article; (JOURNAL ARTICLE))</style></notes></record></records></xml>
