Dipole-dipole interactions in spin-labeled Au nanoparticles as a measure of interspin distances

Article Abstract:

A series of Au nanoparticles modified with a nitroxide-functionalized ligand was prepared with a range of spin-labeled coverage. The X-band electron paramagnetic resonance spectra of frozen solutions of these nanoparticles showed coverage-dependent line-broadening due to dipole-dipole interactions between spin labels.

Size and electric dipole (hyper)polarizability in small cadmium sulfide clusters: an ab initio study on (CdS)(sub n), n=1, 2, and 4

Article Abstract:

The conventional ab initio and B3LYP/DFT calculations are reported for the static electric (hyper)polarizability of small Cds clusters indicates a strong reduction of the mean dipole polarizability with size.Results suggest that DFT methods might predict reliable poloarizability values for large clusters.

Synthesis and characterization of poly(acrylic acid) stabilized cadmium sulfide quantum dots

Article Abstract:

The synthesis, as well as the characterization of poly(acrylic acid) (PAA) stabilized cadmium sulfide (CdS) quantum dots (QD) are explained. These compounds are shown to be extremely stable and luminescent.
