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.

Tunable surface-plasmon-resonance wavelength of silver island films

Chinese Physics B, 2010
This 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.

Resonance wavelengths of silver–gold compound metal island films

Journal of the Optical Society of America B, 1995
The resonance wavelength of a silver–gold compound metal island (CMI) film can be easily defined by the control of the mixture ratio of silver and gold. We have investigated its mechanism by observing the film microstructure with a scanning electron microscope.

Application of plasmonic silver island films in thin-film silicon solar cells

Journal of Optics, 2012
Silver nanoparticles can be used as light scattering elements for enhancing solar cell energy conversion efficiencies. The objective of our work is to gain more insight into the optical properties of silver nanoparticle films and their effect on the performance of solar cells.

Silver Island Films for Write-Once Optical Storage Media

Optical Data Storage, 1994
Recently many write-once (WO) storage media have been proposed and investigated, including organic dye and tellurium based alloy, etc. A metal island film is one of the potential WO storage media. It is composed of nanometer-size metal particles (i.e., islands) and exhibits a high reflectance and large absorptance due to the resonance of free electrons

Excitation spectra of surface-enhanced Raman scattering on silver-island films

Optics Letters, 1982
Both the spectral dependence and the magnitude of the excitation spectra of surface-enhanced Raman scattering are found to be quantitatively related to the absorption spectra for silver-island films. This relationship is maintained even when the local electromagnetic enhancement at the islands is varied by coating the film with a layer of absorbing dye

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-

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 ...

Surface-enhanced second-harmonic generation in C60-coated silver island films

Physics Letters A, 1993
Abstract Surface-enhanced generation of the diffuse and depolarized optical harmonic (SH) upon reflection of laser radiation from C60-coated silver island films is observed. An order of magnitude relative enhancement of the SH response from the coated films with respect to the uncoated ones is found. The nature of the observed effects is discussed.

Raman spectroscopy of carbon monoxide adsorbed on silver island films

Surface Science, 1990
Abstract CO was adsorbed at 17 K on clean silver island films prepared in UHV. The surface enhanced Raman scattering (SERS) spectrum shows besides the stretch band at ∼ 2112 cm−1 of “chemisorbed” CO an unshifted band at ∼ 2139 cm−1 whose intensity saturates at monolayer coverage. It is assigned to “ physisorbed” CO.
