Water-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 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.
متن کاملSynthesis and Applications of Water-Soluble Fluorescent Silver Nanoclusters
Ag nanoclusters consisting of several AQ:1 to a hundred atoms with diameters less than 2 nm show molecule-like properties, including discrete electronic AQ:2 transitions and strong fluorescence. They have received considerable research interest due to their unique optical, electrical and chemical properties and potential applications in chemicaland biosensing. Ag nanoclusters exhibit excellent ...
متن کاملHolographic patterning of fluorescent microstructures comprising silver nanoclusters
Metal nanoclusters, which exhibit extraordinary physical and chemical properties that are different from their bulk counterparts, are highly promising nanomaterials for photonics. Recently, the use of twophoton excitation to fabricate silver nanoclusters in polymers was reported but still lacks speed and flexibility which are imperative for applications such as labeling and spectroscopy. Here, ...
متن کاملOn heterogeneity in fluorescent few-atom silver nanoclusters.
Fluorescent clusters of several Ag atoms are fluorophores with a large set of attractive properties including sub-nanometer size, high fluorescence quantum yield and large Stokes shift. When formed on polymeric scaffolds they exhibit a broad range of heterogeneities in excitation and emission spectra. Addressing this issue we provide detailed spectroscopic studies of these clusters produced by ...
