Microélectronique

Linear and non-linear optical spectroscopy of 'well-behaved' colloidal suspensions of nanocrystal assemblies

The directed self-assembly of nanocrystals in the liquid phase can yield new materials with interesting optical properties for potential applications in medical diagnostics, phototherapy, photoenergy, and the guiding of light. Development of self…

Optical extinction and scattering cross sections of plasmonic nanoparticle dimers in aqueous suspension

Absolute extinction and scattering cross sections for gold nanoparticle dimers were determined experimentally using a chemometric approach involving singular-value decomposition of the extinction and scattering spectra of slowly aggregating gold…

2-dimensional hybrid perovskites activation with an organic luminophore for photovoltaic applications

The excellent optical and electronic properties of hybrid organic-inorganic perovskites make them suitable active materials for optoelectronics devices. Here we focus the attention on the 2D lead halide hybrid perovskites having the general formula …

Electrodeposition of polypyrenes with tunable hydrophobicity, water adhesion and fluorescence properties

The control in surface hydrophobicity and water adhesion is extremely important for various applications in water harvesting, oil/water separation membrane, energy systems or biosensing, for example. Here, for the first time we show that the use of…

Fluorescent core-shell nanoparticles and nanocapsules using comb-like macromolecular RAFT agents: synthesis and functionalization thereof

Fluorescent nanoparticles and nanocapsules (FNPs) were synthesized via a one-pot RAFT miniemulsion process copolymerizing BODIPY-methacrylate and styrene in water. Ultra-bright sub-100 nm core–shell nanoparticles could be obtained with BODIPY…

Photoswitchable Arene Ruthenium Complexes Containing o-Sulfonamide Azobenzene Ligands

A series of arene ruthenium complexes containing ortho-sulfonamide azobenzene ligands were synthesized and found to exhibit uncommon coordination pattern with exocyclic N=N bond. Upon irradiation, these complexes cleanly undergo (E)→(Z)…
