Optical and structural characterization of silver islands films on glass substrates

Vacuum, 2009
Metal islands films (MIFs) of Ag on glass substrates were fabricated by the e-beam evaporation process. The dependence of the surface plasmon (SP) absorption wavelength on the deposition mass thickness and substrate temperature was quantified. The structural and optical characterization of the MIFs, done by spectrometry, grazing incidence small angle X-

Reduced intermolecular energy transfer on silver island films

Chemical Physics Letters, 1988
Abstract Radiationless energy transfer between high quantum efficiency donor and acceptor dye molecules is investigated for different distances between a silver island film and the dye laser by cw fluorescence spectroscopy. We observe reduced donor-acceptor energy transfer efficiency up to island-dye distances of 15 nm due to the enhanced radiative

Singlet Oxygen Phosphorescence Enhancement by Silver Islands Films

The Journal of Physical Chemistry C, 2011
Optical detection of singlet oxygen, a reactive oxygen species that plays a crucial role in a variety of biomedical processes, is hampered by its extremely low emission probability. Using plasmonic effects induced in silver islands films coated with C60, we have been able to enhance the near-IR phosphorescence of singlet oxygen by a factor of ca.

Flexible and optically transparent silver nano-islands film

AIP Conference Proceedings, 2014
We report a cost effective and facile way to synthesize flexible, transparent conductor using oblique angle deposition (OAD). A flexible Ag islands film with transmittance of 28.02 % at 550 nm is obtained with only one step on Polydimethylsiloxane (PDMS) substrate before stretching.

Smart color designs with Ag and Au metal island films: a theoretical study.

Applied Optics
Multilayer structures incorporating silver and gold metal island films embedded in two different dielectrics are designed to achieve the reflectance of three clearly distinct colors, based on the presence of both Au only or the complete absence of the ...

Silver island film substrates for ultrasensitive fluorescence detection of (bio)molecules

Photosynthesis Research, 2015
A silver island film (SIF) substrate was used to demonstrate that Metal-Enhanced Fluorescence (MEF) is a powerful tool to enable detection of emission from (bio)molecules at very low concentrations. The experiments were carried out with the Fenna-Matthews-Olson (FMO) pigment-protein complex from the photosynthetic green sulfur bacterium Chlorobaculum ...

Optical properties of silver island films in the attenuated-total-reflection geometry

Applied Optics, 1986
The absorptances of 633-nm photons by silver island films formed on room temperature substrates were measured in an attenuated-total-reflection geometry by the photoacoustic method as a function of the angle of photon incidence. From the data obtained for s-polarized light ∊″, the effective dielectric function for the direction parallel to the film and

Influence of a magnetic field on the aging rates of island silver films

Journal of Physics D: Applied Physics, 1990
The authors present the results of investigations carried out on the effect of magnetic field on the aging rates of island silver films deposited on glass substrates held at room temperature in a vacuum of 1*10-5 Torr. It is observed that the application of a magnetic field of strength 80 G during and after growth of the island film reduces the aging ...

Vacuum deposition of silver island films on chemically modified surfaces

Journal of Vacuum Science & Technology A: Vacuum, Surfaces, and Films, 2003
The silver island films were vacuum deposited at two different evaporation rates on unmodified indium tin oxide substrates and the substrates modified with molecules containing thiol, pyridyl, and fluorocarbon groups. The films were characterized by UV-visible spectroscopy and scanning electron microscopy.
