Effect of size and light power on the fluorescence yield of rubrene nanocrystals

Rubrene nanocrystals were prepared from a toluene emulsion. For the bigger one (>500nm), the absorption spectrum is deformed at wavelength where the absobance of a single nanocristal is higher that 0.1. The nanocristals exhibit a long lived…

Characterization of alumina surfaces by fluorescence spectroscopy : Part 2. Photophysics of a bound pyrene derivative as a probe of the spatial distribution of reactive hydroxyl groups

In order to characterize and compare the spatial distribution of hydroxyl groups on gamma- and delta-alumina surfaces, a pyrene derivative was covalently grafted on these groups and studied by steady-state and time-resolved fluorescence spectroscopy…

Ingénierie moléculaire et fluorescence : détection de cations lourds et étude de surfaces d'alumines

Ce travail s'inscrit dans une démarche d'ingénierie moléculaire impliquant l'utilisation de sondes fluorescentes, avec un double objectif de détection de cations lourds polluants pour l'environnement et d'étude de surfaces d'alumines. Dans une…

Characterization of alumina surfaces by fluorescence spectroscopy. Part 1. Grafting a pyrene derivative on γ- and δ-alumina supports

With the aim of characterizing the proximity and the distribution of hydroxyl groups on alumina surfaces by fluorescence spectroscopy, a fluorophore containing a pyrene moiety linked to a triethoxysilane group (PPTEOS) was synthesized and grafted on…

Picosecond and nanosecond polychromatic pump-probe studies of bubble growth in carbon-nanotube suspensions

Optical limiting in carbon-nanotube suspensions, whose origin lies in a strong nonlinear scattering due to solvent vapor bubbles and sublimation of the nanotubes, is investigated in the picosecond and nanosecond regimes by polychromatic pump-probe…

Enhancement of non-resonant nonlinear refractive index with reduction of absorption in push-pull molecules by reduction of their donor group strength

We show that reducing the strength of the amine donor group in push-pull molecules increases their non-resonant non-linear refractive index in the infrared although the blue-shift of their visible absorption peak, associated with the donor strength…

Caractérisation de billes de latex fluorescentes pour l'élaboration de nanocapteurs

Nous avons montré la faisabilité d 'une approche de capteur où les fonctions de détection et de signalisation sont séparées. Nous avons choisi comme supports lumineux des nanosphères fluorescentes. Elles servent de transducteurs. Nous avons exploré…
