Enhanced molecular fluorescence near thick Ag island film of large pseudotabular nanoparticles

Article Abstract:

A highly reflective thick Ag island film (TAIF) sputter-grown on mica, consisting of unique large pseudotabular nanoislands, 60-200 nm across and 30-60 nm thick, produced an unusually strong surface enhanced fluorescence (SEF) for rhodamine dyes situated very close to the metal surface. The estimated SEF quantum yield in the low dye coverage limit suggests a markedly high radioactive yield of the induced dipole in TAIF around ~0.5.

A simple two-phase route to silver nanoparticles/polyaniline structures

Article Abstract:

Novel silver nanoparticles/polyaniline composites are obtained through a two-phase water/toluene interfacial reaction. The conductivity and current-voltage characteristics of nanocomposites have indicated that different properties result from the different structures in which the nanocomposites are formed.

Dithiocarbamate-capped silver nanoparticles

Article Abstract:

Didecylamine dithiocarbamates were used as the protecting ligands to synthesize nanometer-sized silver particles. The particle core dimensions were found to be sensitively varied by the initial ligand-metal feed ratio, as attested by transmission electron microscopic measurements.
