Light-induced spin crossover probed by ultrafast optical and X-ray spectroscopies

Majed Chergui, Andrea Cannizzo, Wojciech Gawelda, Van Thai Pham, Amal El Nahhas, Renske Marjan van der Veen

The photoinduced energy and structural relaxation of aq. iron(II)-tris-bipyridine ([FeII(bpy)3]2+), upon excitation into its singlet metal-to-ligand charge transfer (1MLCT) band, and the population of its short-lived (?0.6 ns) high-spin excited state have ...

Terahertz photonic crystal quantum cascade lasers

Romuald Houdré, Hua Zhang, Jérôme Faist

We combine photonic crystal and quantum cascade band engineering to create an in-plane laser at terahertz frequency. We demonstrate that such photonic crystal lasers strongly improve the performances of terahertz quantum cascade material in terms of thresh ...

Excited-State Dynamics of Donor−Acceptor Bridged Systems Containing a Boron−Dipyrromethene Chromophore: Interplay between Charge Separation and Reorientational Motion

Natalie Renuka Banerji, Eric Vauthey

The excited-state dynamics of a series of electron donor−acceptor bridged systems (DABS) consisting of a boron−dipyrromethene chromophore covalently linked to a dinitro-substituted triptycene has been investigated using femtosecond time-resolved spectrosco ...

Observation of the Solvent Shell Reorganization around Photoexcited Atomic Solutes by Picosecond X-ray Absorption Spectroscopy

Majed Chergui, Wojciech Gawelda, Van Thai Pham

We report on the observation of the solvation shell rearrangement after abstraction of the electron from aq. I- in a laser pump/X-ray probe expt. by recording the X-ray absorption L1- and L3-edge spectra, 50 ps after laser excitation. The L1-edge spectra c ...

Real-Time Birefringence Measurement with Digital Holographic Microscopy

Christian Depeursinge, Yves Bellouard, Tristan Colomb, Jonas Kühn, Florian Charrière

Digital holographic microscopes using two orthogonal polarized reference waves provides real-time polariscopes. Birefringence induced by internal stress is imaged in optical fibers and in fused silica substrates, where lines are written with low-energy fem ...

Model-Based deduction of CMYK Surface Coverages from Visible and Infrared Spectral Measurements of Halftone Prints

Roger Hersch, Thomas Bugnon, Mathieu Brichon

The Yule-Nielsen modified Spectral Neugebauer reflection prediction model enhanced with an ink spreading model provides high accuracy when predicting reflectance spectra from ink surface coverages. In the present contribution, we try to inverse the model, ...

Analysis of UWB antennas for carrier-based UWB impulse radio

Anja Skrivervik, Gabriela Quintero Diaz De Leon

A Carrier-based UWB pulse is compared with the commonly used Gaussian pulse. Two antenna systems are simulated and measured in frequency domain. The impulse response and the Power Spectral Density (PSD) of both studied pulses are obtained. The effect of ea ...

Ultrafast-based projection-reconstruction three-dimensional nuclear magnetic resonance spectroscopy

Mor-Miri Mishkovsky

Recent years have witnessed increased efforts toward the accelerated acquisition of multidimensional nuclear magnetic resonance (nD NMR) spectra. Among the methods proposed to speed up these NMR experiments is "projection reconstruction," a scheme based on ...
