Quenching dynamics in CdSe nanoparticles: surface-induced defects upon dilution

We have analyzed the decays of the fluorescence of colloidal CdSe quantum dots (QDs) suspensions during dilution and titration by the ligands. A ligand shell made of a combination of trioctylphosphine (TOP), oleylamine (OA), and stearic acid (SA)…

Silver nanoparticles coated with thioxanthone derivative as hybrid photoinitiating systems for free radical polymerization.

A new type of photoinitiator for free radical polymerization was synthesized and characterized. 2-(11-Mercaptoundecyloxy)thioxanthone (1) was anchored at the surface of silver nanoparticles (NPs), and the interaction of plasmon field generated in…

Mixed Copper, Silver, and Gold Cyanides, (MxM '(1-x))CN: Tailoring Chain Structures To Influence Physical Properties

Binary mixed-metal variants of the one-dimensional MCN compounds (M = Cu, Ag, and Au) have been prepared and characterized using powder X-ray diffraction, vibrational spectroscopy, and total neutron diffraction. A solid solution with the AgCN…

Electrofluorochromism of a ruthenium complex investigated by time resolved TIRF microscopy coupled to an electrochemical cell

This paper describes the use of TIRF microscopy coupled to electrochemistry to investigate the electrofluorochromic properties of a new bipyidine-phenanthroline ruthenium complex. A reversible electrochemical modulation of luminescence is observed…

Study on novel photochromic systems based on chromophores with six-membered ring as central ethene bridge

Une série de bisthiényléthènes (BTE), chromophores photochromes, à différents ponts éthène centraux a été synthétisée. Jusque là, la conception rationnelle des BTE a reposé sur la nature des substituants des groupes latéraux. Dans notre travail,…
