Synthesis and Characterization of Colloidal Fluorescent Silver Nanoclusters

Langmuir, 2012
Ultrasmall water-soluble silver nanoclusters are synthesized, and their properties are investigated. The silver nanoclusters have high colloidal stability and show fluorescence in the red. This demonstrates that like gold nanoclusters also silver nanoclusters can be fluorescent.

Melting and Freezing of Free Silver Nanoclusters

Advanced Materials Research, 2011
The melting and freezing with two different cooling rates of AgN (N= 140, 360, 532, 784, and 952) nanoclusters are simulated by using molecular dynamics technique with the frame work of embedded atom method. The potential energy as a function of temperature is obtained and the structural details are analyzed.

Silver Sulfide Nanoclusters and the Superatom Model

The Journal of Physical Chemistry C, 2015
The superatom model of electron-shell closings has been widely used to explain the stability of noble-metal nanoclusters of few nanometers, including thiolate-protected Au and Ag nanoclusters. The presence of core sulfur atoms in silver sulfide (Ag–S) nanoclusters renders them a class of clusters with distinctive properties as compared to typical noble-

Fluorescent silver nanoclusters as DNA probes

Nanoscale, 2013
Fluorescent silver nanoclusters (few atoms, quantum sized) have attracted much attention as promising substitutes for conventional fluorophores. Due to their unique environmental sensitivities, new fluorescent probes have been developed based on silver nanoclusters for the sensitive and specific detection of DNA.

Plasmon Coupling in DNA-Assembled Silver Nanoclusters

Journal of the American Chemical Society, 2021
Quantum-size metal clusters with multiple delocalized electrons could support collective plasmon excitation, and thus, theoretically, coupling of plasmons in the few-atom limit might exist between assembled metal clusters, while currently few experimental observations about this phenomenon have been reported.

The solvent effect on the luminescence of silver nanoclusters

Physical Chemistry Chemical Physics, 2013
The solvent effect on the luminescence properties of highly stable water-soluble silver nanoclusters is discussed in this study. The polymer nanosphere templates swollen by organic solvents lead to the changes in the surrounding environments of silver nanoclusters, thus resulting in a significant influence on their luminescence.
