Influence of a magnetic field on the aging rates of island silver films
Journal of Physics D: Applied Physics, 1990The 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, 2003The 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.

Flourescent lifetimes and yields of molecules adsorbed on silver-island films
Journal of Luminescence, 1981Abstract When molecules are absorbed on silver island films, their flourescent lifetimes are found to be shortened by about three orders of magnitude and their decay is found to be non-exponential in time. This behavior is a result of the electromagnetic interaction between the molecules and the silver islands.

Journal of Colloid and Interface Science, 2001
Surface-enhanced Raman scattering(SERS) of the Rhodamine 123 (Rh 123) molecule on ion-induced silver colloids has been studied. A time-dependent study of the SER spectra at a particular pH confirms charge transfer interaction between the probe molecule and the metal.

Surface decoration of Langmuir-Blodgett films with evaporated silver islands
Thin Solid Films, 1989Abstract Silver was evaporated on Langmuir-Blodgett (LB) films of cadmium arachidate and phthalocyaninato-polysiloxane. Electron microscopy and UV-visible- near IR absorption spectroscopy show that the island formation and the sticking probability of silver depend on the thickness of the cadmium arachidate films.

Surface-enhanced second-harmonic generation in C60-coated silver island films
Physics Letters A, 1993Abstract 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.

Infrared Absorption Enhancement of C 60 by Overlaying Thin Silver Island Films
Applied Spectroscopy, 2004Normal-incidence infrared absorption has been observed for silver overlaid C 60 thin films formed on surface-oxidized Si(111) substrates as a function of the silver or C 60 film thickness. The absorption spectra exhibit bands at 1429 and 1180 cm

Size Effect on the Width of Plasma Resonance Absorption of Silver Island Films
Journal of the Physical Society of Japan, 1982The size dependence of the half width of the optical plasma resonance absorption of silver island films has been investigated at 293 K. Below a diameter of about 14 A the deviation from the classical prediction was observed. Considering the average energy level spacing and the level broadening due to scatterings, this deviation was attributed to the ...
