Design and fabrication of selective thin film absorbers on the basis of silver island films

Vakuum in Forschung und Praxis, 2022
S.53-56The combination of a metal island film with a dielectric multilayer represents a novel approach to the preparation of spectrally selective absorbers.

Giant third optical harmonic generation in island silver films

Journal of Experimental and Theoretical Physics Letters, 2004
Giant third optical harmonic (TH) generation has been experimentally observed in island silver films. The TH intensity in the island silver films studied is more than two orders of magnitude higher than the value observed for the smooth surface of a ...

Decreasing photobleaching by silver island films: application to muscle [PDF]

Analytical Biochemistry, 2007
Recently it has become possible to study interactions between proteins at the level of single molecules. This requires collecting data from an extremely small volume, small enough to contain one molecule-typically of the order of attoliters (10(-18) L).

Immobilization of enzymes to silver island films for enhanced enzymatic activity [PDF]

Journal of Colloid and Interface Science, 2014
The performance of the enzyme-based biosensors depends on the enzymatic activity and the use of an appropriate technique for immobilization of enzymes. The incorporation of silver island films (SIFs) into the enzyme-based biosensors is expected to enhance the enzymatic activity and to increase the detectability of analytes of interest.Two enzymes, β ...

Enhanced Fluorescence Images for Labeled Cells on Silver Island Films [PDF]

Langmuir, 2008
Silver island films (SIFs) were deposited on glass substrates to serve as supports. T-Lymphocytic (PM1) cell lines were labeled by Alexa Fluor 680-dextran conjugates on the membranes or by YOYO in the nuclei. The fluorescence images of the cell lines were recorded in the emission intensity and lifetime using scanning confocal microscopy.

Plasmonics and single‐molecule detection in evaporated silver‐island films

Annalen der Physik, 2012
AbstractThe plasmonic origin of surface‐enhanced Raman scattering (SERS) leads to the concept of hotspots and plasmon coupling that can be realized in the interstitial regions, or on specially engineered, silver and gold nanostructures. It is also possible to achieve spatial locations of high local field or hotspots on silver‐island films (SIF ...

Effective optical constants of evaporated silver and copper island ultrathin films

, 2022
Paper WA.10The optical properties of copper and silver island films are quantified in terms of effective optical constants. Knowledge of these effective constants allows straightforward design calculations of island film based multilayer ...

Enhancement of FITC Fluorescence by Silver Colloids and Silver Island Films

Acta Physica Polonica A, 2008
Silver colloids and silver island fllms as °uorescence enhancement sys-tems are the subject of this paper. Enhancement of °uorescence of moleculesplaced near metallic nanoparticles is a result of resonance interaction of ex-citing and emitted lights with surface plasmons. Two models explainingthis phenomenon are presented.

Angular-dependent metal-enhanced fluorescence from silver island films [PDF]

Chemical Physics Letters, 2008
In this Letter we report the observation of angular-dependent metal-enhanced fluorescence (MEF) from fluorophores deposited onto silver island films (SiFs). When illuminated with laser light (473nm) at angles of 45° and 90° from the surface, SiFs scattered light at wide observation angles biased by the direction of the incident light.

Electrochemical deposition of SERS active nanostructured silver films

International Journal of Electrochemical Science, 2013
An electrochemical multiple scan cyclic voltammetry (CV) method was used to prepare surface- enhanced Raman scattering (SERS) active silver island films to investigate the effect of potential scan rate and number of CV scans on the SERS performance.
