Charge-transfer transition in two-dimensionalCs[Co(3−cyanopyridine)2][W(CN)8]∙H2Oas investigated by angle-resolved x-ray diffraction

Ultrafast inter-ionic charge transfer of transition-metal complexes mapped by femtosecond X-ray powder diffraction.

The transient electronic and molecular structure arising from photoinduced charge transfer in transition metal complexes is studied by X-ray powder diffraction with a 100 fs temporal and atomic spatial resolution. Crystals containing a dense array of Fe(II)-tris(bipyridine) ([Fe(bpy)3](2 +)) complexes and their [Formula: see text] counterions display pronounced changes of electron density that ...

Fusion bonding of Si wafers investigated by x ray diffraction

Charge transfer in nanocrystalline-Au/ZnO nanorods investigated by x-ray spectroscopy and scanning photoelectron microscopy

O Kand Zn and Au L3-edge x-ray absorption near-edge structure XANES , x-ray emission spectroscopy XES , and scanning photoelectron microscopy SPEM are performed to investigate the electronic structure of ZnO nanorods with nanocrystalline nc -Au particles grown on the surfaces. The XANES spectra of nc-Au/ZnO nanorods reveal the decrease of the number of both O 2p and Zn 4s /3d unoccupied states ...

Excited-state structure by time-resolved X-ray diffraction.

X-ray crystallography has traditionally been limited to the study of the ground-state structure of molecules and solids. Recent technical advances are removing this limitation as demonstrated here by a time-resolved stroboscopic study of the photo-induced 50 micros lifetime excited triplet state of the [Pt(2)(pop)(4)](4-)ion [pop = pyrophosphate, (H(2)P(2)O(5))(2-)], performed at helium tempera...

Ultrafast structural changes measured by time-resolved X-ray diffraction

High-intensity X-ray pulses from third-generation synchrotron sources make it possible to study the temporal dynamics of rapidly evolving materials. We report a study of rapid and reversible disordering of the structure of an InSb crystal induced by an ultrashort laser pulse. A novel crosscorrelation detection technique is described, which allowed us to observe rapid changes in X-ray diffractio...
