Femtosecond XANES Study of the Light-Induced Spin Crossover Dynamics in an Iron(II) Complex
Ch. Bressler,Christopher J. Milne,Van-Thai Pham,Amal Elnahhas,R. M. van der Veen,R. M. van der Veen,Wojciech Gawelda,Wojciech Gawelda,Steven L. Johnson,Paul Beaud,Daniel Grolimund,Maik Kaiser,Maik Kaiser,Camelia N. Borca,Gerhard Ingold,Rafael Abela,Majed Chergui +16 more
TL;DR: These results resolve a long-standing issue about the population mechanism of quintet states in iron(II)-based complexes, which are identified as a simple 1MLCT→3 MLCT→5T cascade from the initially excited state.
Journal ArticleDOI
Photochemically Grown Silver Nanoparticles with Wavelength-Controlled Size and Shape
TL;DR: In this article, the authors used light to transform a colloidal solution of spherical silver nanoparticles into larger nanoparticles of a different shape by choosing the wavelength(s) of light used to drive the photochemical growth.
Journal ArticleDOI
Ultrafast X-ray absorption spectroscopy
Christian Bressler,Majed Chergui +1 more
TL;DR: Ultrafast x-ray techniques using diffraction and absorption are discussed with an emphasis on the absorption techniques, and sources and detectors for use in x-rays absorption spectroscopy are reviewed.
Journal ArticleDOI
Ultrafast Nonadiabatic Dynamics of [FeII(bpy)3]2+ in Solution
Wojciech Gawelda,Andrea Cannizzo,Van-Thai Pham,Frank van Mourik,Christian Bressler,Majed Chergui +5 more
TL;DR: A simple model of avoided crossings between singlet and triplet potential curves, induced by the strong spin-orbit interaction is proposed, which concludes that the ultrafast relaxation of aqueous iron(II)-tris(bipyridine) upon excitation into the singlet metal-to-ligand charge-transfer band can be described by the Fermi golden rule, despite its high value.
Journal ArticleDOI
Sub-50-fs photoinduced spin crossover in [Fe(bpy)(3)](2+)
Gerald Auböck,Majed Chergui +1 more
TL;DR: The results show that even though the SCO process in Fe(II) complexes represents a strongly spin-forbidden (ΔS = 2) two-electron transition, spin flipping occurs at near subvibrational times and is intertwined with the electron and structural dynamics of the system.
