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…

Photophysics of Calcium Green 1 in vitro and in live cells

The absolute measurement of calcium activity in cells is hindered by the presence of di†erent forms of the probe (adsorbed, protonated). Time-resolved Ñuorescence spectroscopy can be a sensitive technique to separate contaminating forms of the probe…

New Octupolar Star-Shaped Strucures for Quadratic Nonlinear Optics

Two new classes of octupolar nonlinear chromophores, deriving from 1,3,5-triazines and oligothienylic crystal violet analogues, have been synthesized and their nonlinear properties investigated using the harmonic light scattering experiment. The…

Synthesis, Crystal Structure, and Second-Order Nonlinear Optical Properties of a New Phase-Matchable Cyanine Dye

A new chiral hemicarboxonium salt, (ephem)(BF4), was synthesized by action of α-1-((methylamino)ethyl)benzyl alcohol, (−)-ephedrine, on a carboxonium tetrafluoroborate salt. The compound crystallizes in monoclinic space group P21. a = 11.153(1) Å, b…
