Journal ArticleDOI
Measurement of the Radiative and Nonradiative Decay Rates of Single CdSe Nanocrystals through a Controlled Modification of their Spontaneous Emission
TL;DR: The results demonstrate that the fluorescence quantum efficiency, determined at the single-molecule level, is 98% in average, far above the value expected from conventional ensemble experiments.
Journal ArticleDOI
Emission characterization of a single CdSe-ZnS nanocrystal with high temporal and spectral resolution by photon-correlation Fourier spectroscopy.
TL;DR: A spectroscopic study of single colloidal CdSe/ZnS nanocrystals at low temperature using photon-correlation Fourier spectroscopy, a technique based on measuring the correlations of the intensities detected at the outputs of a Michelson interferometer.
Journal ArticleDOI
Emission properties of single CdSe/ZnS quantum dots close to a dielectric interface
TL;DR: In this paper, the effect of a dielectric interface on the emission of individual semiconductor quantum dots (QDs) was studied by placing a single nanoparticle successively close and far from an interface, enabling a direct comparison of its fluorescence properties.
Journal ArticleDOI
Controlled modification of single colloidal CdSe/ZnS nanocrystal fluorescence through interactions with a gold surface
Céline Vion,Piernicola Spinicelli,Laurent Coolen,Catherine Schwob,Jean-Marc Frigerio,J.-P. Hermier,Agnès Maître +6 more
TL;DR: Single colloidal CdSe/ZnS nanocrystals are deposited at various distances from a gold film in order to improve their performance as single photon sources andPhoton antibunching is demonstrated and the experimental curves are accurately fitted by theoretical equations.
Journal ArticleDOI
Photon-correlation Fourier spectroscopy.
TL;DR: A method to probe the spectral fluctuations of a transition over broad ranges of frequencies and timescales with the high spectral resolution of Fourier spectroscopy, and a temporal resolution as high as the excited state lifetime, even in the limit of very low photocounting rates.
