Plasma radiation for atmospheric entry at Titan: Emission spectroscopy measurements and numerical rebuilding

Pénélope Leyland, Raffaello Sobbia

Emission spectroscopy measurements on a plasma representative of Titan atmosphere composition were obtained in the Inductively Coupled Plasma wind tunnel facility (VKI-Minitorch) at the von Karman Institute in Belgium. Temperatures ranged from 3600 to 5000 ...

Near-UV to red-emitting charged bis-cyclometallated iridium(III) complexes for light-emitting electrochemical cells

Michael Graetzel, Mohammad Khaja Nazeeruddin, Rosario Scopelliti, Davide Di Censo

Herein we report a series of charged iridium complexes emitting from near-UV to red using carbene-based (NC)-C-boolean AND: ancillary ligands. Synthesis, photophysical and electrochemical properties of this series are described in detail together with X-ra ...

Ultrafast Relaxation of the Poly(3-hexylthiophene) Emission Spectrum

Natalie Renuka Banerji, Eric Vauthey

The femtosecond-resolved evolution of the emission spectrum of the important conjugated polymer poly(3-hexylthiophene) (P3HT) is presented. Detailed fluorescence up-conversion spectroscopy was performed on P3HT solid-state films and on P3HT in chlorobenzen ...

Fluorophore-doped xerogel antiresonant reflecting optical waveguides

Jürgen Brugger, Victor Javier Cadarso Busto

Rhodamine B and Alexa Fluor 430 fluorophores have been used as doping agents for xerogel waveguides defined over an antiresonant (ARROW) filter. This configuration has a significant level of integration, since it merges the waveguide, the light emitter and ...

An inconvenient influence of iridium(III) isomer on OLED efficiency

Michael Graetzel, Mohammad Khaja Nazeeruddin, Filippo de Angelis, Davide Di Censo

The recently reported heteroleptic cyclometallated iridium(III) complex [Ir(2-phenylpyridine)(2)(2-carboxy-4-dimethylaminopyridine)] N984 and its isomer N984b have been studied more in detail. While photo- and electrochemical properties are very similar, D ...

Propriétés optiques de petits agrégats de métaux nobles en matrice de néon

Sylvain Lecoultre

The optical properties of small noble metal clusters have been studied by absorption and fluorescence for sizes between 1 and 10 atoms. The experimental technique consists in depositing size-selected clusters in a neon matrix and analyzing with a spectrome ...
