Long-lived electron emission reveals localized plasmon modes in disordered nanosponge antennas. - In: Light : Science & Applications. - London : Nature Publishing Group, ISSN 20477538, Bd. 6Bd. 6 (2017), (20. Okt.), e17075, insges. 8 S.

We report long-lived, highly spatially localized plasmon states on the surface of nanoporous gold nanoparticles-nanosponges-with high excitation efficiency. It is well known that disorder on the nanometer scale, particularly in two-dimensional systems, can lead to plasmon localization and large field enhancements, which can, in turn, be used to enhance nonlinear optical effects and to study and exploit quantum optical processes. Here, we introduce promising, three-dimensional model systems for light capture and plasmon localization as gold nanosponges that are formed by the dewetting of gold/ silver bilayers and dealloying. We study light-induced electron emission from single nanosponges, a nonlinear process with exponents of n approximate to 5...7, using ultrashort laser pulse excitation to achieve femtosecond time resolution. The long-lived electron emission process proves, in combination with optical extinction measurements and finite-difference time-domain calculations, the existence of localized modes with lifetimes of more than 20 fs. These electrons couple efficiently to the dipole antenna mode of each individual nanosponge, which in turn couples to the far-field. Thus, individual gold nanosponges are cheap and robust disordered nanoantennas with strong local resonances, and an ensemble of nanosponges constitutes a meta material with a strong polarization independent, nonlinear response over a wide frequency range.

Lorentz Force Velocimetry measurements using HTS bulk magnet system. - In: Workshop Elektroprozesstechnik / Workshop Elektroprozesstechnik (Ilmenau) : 2017.10.05-06. : 5.-6. Oktober 2017, Seminar- und Ferienhaus "Zur Talsperre", An der Talsperre 1, D-98693 Ilmenau - Ortsteil Heyda : Tagungsband. - Ilmenau : Förderkreis Elektrowärme Ilmenau e.V., (2017), 9, insges. 8 S.

An experimental demonstration of the Lorentz force velocimetry (LFV) technique using high-temperature superconducting (HTS) bulk magnet system (MS), acting as trapped field magnets, is reported. Besides the experimental results on the Lorentz force, FL, induced by a vertically aligned cylindrical moving metal rod through the oppositely arranged HTS-MS, the HTS-MS design as well as activation procedure, including refrigeration and magnetization, along with further suggestions for improvements are discussed.

Im vorliegenden Beitrag werden Mikrowellen absorbierende AII/BIV substituierte Bariumhexaferrite (BHF) in einer glasigen Matrix durch Schnellkühlung der Schmelze mit der Zusammensetzung 40 Mol-% BaO + 27-(y+x) Mol-% Fe2O3 + x Mol-% AIIO + y Mol-% BIVO2 + 33 Mol-% B2O3 und anschließender bottom-up-Steuerung der Keimbildung und des Kristallwachstums (Glaskristallisationstechnik) synthetisiert. Dabei werden Substituent (paramagnetische Kationen: MnII, FeII, CoII, diamagnetisches Kation: TiIV) und Temperbedingungen (Temperatur, Haltezeit) systematisch variiert und wesentliche Struktur-Eigenschafts-Beziehungen zur Synthese der substituierten Bariumhexaferrite aufgeklärt. Die synthetisierten BHF-Pulver sind für die Herstellung von Bond/ Disbond-on-Command Klebstoffen und von maßgeschneiderten Absorbermaterialien sowie für sensorische magnetische Anwendungen geeignet. Die Herstellung der BHF-Pulver wurde im Labormaßstab erfolgreich getestet. Lösungsansätze für die industrielle Produktion werden vorgestellt.
