The effect of substrate vibration on mobility coalescence in silver island films
Thin Solid Films, 1997Abstract We present the results of the investigations carried out on the effect of ultrasonic vibration of the substrate during deposition and during aging on the instabilities of island silver films deposited on glass held at room temperature in a vacuum of 2 × 10 −6 Torr.

Optical and structural characterization of silver islands films on glass substrates
Vacuum, 2009Metal 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-

Preparation of silver island films with tunable surface plasmon resonance
SPIE Proceedings, 2012Silver (Ag) island films have been prepared by pulsed laser ablation in vacuum using a XeCl excimer laser. The effects of the number of ablation pulses, the temperature and time of post-annealing on morphology and surface plasmons properties of the prepared Ag island films were investigated by extinction spectra and scanning electron microscopy.

Tunable surface-plasmon-resonance wavelength of silver island films
Chinese Physics B, 2010This paper experimentally and theoretically investigates the effect of the underlayer medium on tuning of the surface plasmon resonance (SPR) wavelength of silver island films, and the effect of substrate temperature on the morphologies and optical properties of the films.

Reduced intermolecular energy transfer on silver island films
Chemical Physics Letters, 1988Abstract 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, 2011Optical 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.

Thickness-gradient dependent Raman enhancement in silver island films
Applied Physics Letters, 2009We show evidence of a dependence of the enhancement of the Raman scattering cross section on the length of the gradient in graded silver island films. A factor-of-three increase in the Raman signal is observed for gradients with length of the order of 0.5 mm when compared to gradients of the order of 9 mm.

Flexible and optically transparent silver nano-islands film
AIP Conference Proceedings, 2014We 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 OpticsMultilayer 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, 2015A 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 ...
