TL;DR: In this paper, a cascaded energy transfer structure made of semiconductor nanocrystals is proposed, where optical excitations efficiently transfer along the band gap gradient and are finally captured by the largest nanocrystal.

TL;DR: In this article, the authors focus on the narrow homogeneous line width of only 180 meV and show that the particle plasmon resonance responds more sensitively to changes in the environment, the biological spectral window is accessible and the scattering spectra show sharper resonances.

TL;DR: In this article, a single particle level spectral analysis of spherical CdSe nanocrystals capped by a CdS rod-like shell was carried out and the results showed a high degree of correlation between the emission energy, spectral linewidth, phonon coupling strength, and emission intensity of the single nanocrystal.

TL;DR: In this article, a model of strongly luminescent monodisperse CdSe nanocrystals in which a few Se atoms are substituted with Te atoms (CdSe:Te) provide a model system for studies of both band-edge and trap-related luminescence.

TL;DR: In this article, the effect of the average donor−acceptor spacing on the time-resolved fluorescence dynamics of single donor-acceptor pairs was investigated, and it was shown that as the acceptor concentration decreases, both the number of donors observed and the average donors intensity increase due to an increase in nanocrystal fluorescence lifetime.
