Plasmons in supported size-selected silver nanoclusters.
The plasmonic behavior of size-selected supported silver clusters is studied by surface second harmonic generation spectroscopy for the first time. A blue shift of ∼0.2 eV in the plasmon resonance is observed with decreasing cluster size from Ag55 to Ag9. In addition to the general blue shift, a nonscalable size-dependence is also observed in plasmonic behavior of Ag nanoclusters, which is attr...
متن کاملPlasmons in Supported Size-Selected Silver Nanoclusters: Supporting Information
The investigation of size dependent effects of supported clusters with integral methods like optical spectroscopy demands a low surface coverage so that agglomeration can be excluded. In addition the plasmon resonance depends strongly on interparticle interactions if the distance between neighboring particles is too small1,2. The threshold value for our experimental setup was determined experim...
متن کاملWater-soluble fluorescent silver nanoclusters.
Ag nanoclusters consist of several to roughly a hundred atoms and possess sizes comparable to the Fermi wavelength of electrons; they exhibit molecule-like properties, including discrete electronic transitions and strong fluorescence. These nanoclusters are of significant interest because they provide the bridge between atomic and nanoparticle behavior in noble metals. Since the first observati...
متن کاملColor tunability and electrochemiluminescence of silver nanoclusters.
Colorful clusters: Silver nanoclusters consisting of only a few atoms exhibit large chemical-environment-responsive shifts of their optical absorption and emission bands, that is, large solvatochromism (see picture). The photophysical characteristics and electrochemiluminescence of the Ag clusters give them remarkable advantages over larger nanoparticles in applications such as molecular sensing.
متن کاملA complementary palette of fluorescent silver nanoclusters.
We report the synthesis and photophysical properties of silver-nanoclusters templated on DNA, with fluorescence excitation and emission at distinct wavelengths that are tuned to common laser excitation wavelengths.
