Neutron/gamma pulse shape discrimination in plastic scintillators: Preparation and characterization of various compositions

This work deals with the preparation and evaluation of plastic scintillators for neutron/gamma pulse shape discrimination (PSD). We succeeded in developing a plastic scintillator with good neutron/gamma discrimination properties in the range of what…

Efficient Sensing of Explosives by Using Fluorescent Nonporous Films of Oligophenyleneethynylene Derivatives Thanks to Optimal Structure Orientation and Exciton Migration

The fluorescence of thin films of a diimine-substituted phenyleneethynylene compound can be efficiently quenched by nitroaromatic vapors, which is not the case for the unsubstituted parent compound. Thin-film porosity is usually considered to be an…

Étude des phénomènes de discrimination neutron/gamma dans les scintillateurs plastiques

Le sujet de cette thèse est né de l'observation de phénomènes incompris des mécanismes à l'origine des très faibles efficacités de discrimination neutron/gamma (n/g) dans les scintillateurs plastiques en comparaison à leurs homologues liquides. Le…

2-Substituted vs 4-substituted-9,9′-spirobifluorene host materials for green and blue phosphorescent OLEDs: a structure-property relationship study

We report a structure-property relationship study of four 9,9′-spirobifluorene (SBF) derivatives (4-5Pm-SBF, 2-5Pm-SBF, 4-Ph-SBF and 2-Ph-SBF), substituted with either phenyl or pyrimidine at the \C2\ or \C4\ position of the \SBF\ core. Structural,…

Alternated bimetallic [Ru–M] (M = Fe2+, Zn2+) coordination polymers based on [Ru(bpy)3]2+units connected to bis-terpyridine ligands: synthesis, electrochemistry and photophysics in solution or in thin film on electrodes

Two alternated bimetallic Ru–Fe and Ru–Zn coordination polymers, [{RuII(bpy)2(L2)MII}n]4n+ (M = Fe2+, Zn2+), were synthesized using the [Ru(bpy)2(L2)]2+ (bpy = 2,2′ bipyridine) complex as a building block, in which L2 is a bipyridine ligand…
