Soft X-ray emission spectroscopy

Journal of Electron Spectroscopy and Related Phenomena, 1998
Abstract New opportunities for soft X-ray emission spectroscopy using monochromatized synchrotron radiation are illustrated with recent results from the Julich and Uppsala groups. The classical interpretation in terms of local partial density of states is instrumental in gaining information about technically relevant materials, and especially the ...

Time-Resolved X-Ray Emission Spectroscopy

International Conference on Ultrafast Phenomena, 2010
We present ultrafast x-ray emission studies of photoexcited aqueous iron tris-bipyridine with 70 ps temporal resolution to monitor the spin state changes in this spin-crossover complex.

X-ray- and electron-induced infrared emission spectroscopy

Review of Scientific Instruments, 2009
We demonstrate the use of Fourier transform infrared (IR) spectroscopy for midinfrared emission measurements following x-ray or electron excitation. Spectra from an InAs low band-gap semiconductor film, which emits in the IR from 3000 to 3400 cm−1, are presented. There is good agreement between the present results and previously published laser-excited

Resonant X-Ray Emission Spectroscopy of Molecular Oxygen

Physical Review Letters, 1996
Resonant soft x-ray emission spectroscopy has been applied to study the issue of symmetry breaking upon core-hole excitation in molecular oxygen. The results provide direct evidence that the inversion symmetry is not broken in the core-excited states.

X-ray Emission Spectroscopy of Nitrogen-Rich Compounds

The Journal of Physical Chemistry A, 2011
Nonresonant X-ray emission spectroscopy was used to compare the nitrogen-rich compounds ammonium nitrate, trinitrotoluene, and cyclotrimethylene-trinitramine. They are representative of crystalline and molecular structures of special importance in industrial and military applications. The spectral signature of each substance was analyzed and correlated

Electronic structure of LaSrMnO4: X-ray photoelectron spectroscopy and x-ray emission spectroscopy studies

Journal of Applied Physics, 2006
We present a comprehensive investigation of the valence band of the single-layered manganite LaSrMnO4. X-ray photoelectron spectroscopy and x-ray emission spectroscopy were used to reveal a detailed picture of the total and partial densities of states in this compound. The results are discussed in the light of available theory.

Stimulated X-ray emission spectroscopy

Photosynthesis Research
We describe an emerging hard X-ray spectroscopy technique, stimulated X-ray emission spectroscopy (S-XES). S-XES has the potential to characterize the electronic structure of 3d transition metal complexes with spectral information currently not reachable and might lead to the development of new ultrafast X-ray sources with properties beyond the state ...

X-Ray Emission Spectroscopy

1981
This paper reviews the applicability of x-ray emission spec-troscopy as a tool for studying the electronic structure of molecules and solids. The wavelengths of interest cover the range from about 1 A (12 000 eV) up to 600 A (20 eV). After a general introduction the basic principles of the spectrometers used in x-ray spectroscopy are described.

Pyroelectric X‐ray application to X‐ray absorption and emission spectroscopies

X-Ray Spectrometry, 2012
Pyroelectric X‐ray generator of Amptek Inc. was used for X‐ray absorption spectroscopy as well as X‐ray fluorescence analysis. The white X‐ray radiation from the pyroelectric crystal was used for X‐ray absorption measurement by using an Si‐PIN X‐ray detector. X‐ray absorption K‐edge spectra of transition metal thin films could be measured.

X-ray-emission-threshold-electron coincidence spectroscopy

Journal of Electron Spectroscopy and Related Phenomena, 2004
Using a penetration-field threshold photoelectron (TPE) analyzer and efficient photon detectors X-ray-emission-threshold-electron coincidence (XETECO) spectroscopy has been developed to a point where peak shape analysis becomes meaningful. The spectra can, on the present level of accuracy, be interpreted as conventional TPE spectra free from post ...
