Alteration of X‐Ray Emission Band Spectrum Under Bragg Diffraction

X-Ray Spectrometry, EarlyView.
ABSTRACT We use a Zr/Si multilayer presenting a gradient of period to probe the shape of the Si L2,3 emission band (maximum around 92 eV) in and out of Bragg conditions. The sample was prepared by magnetron sputtering and its reflectance measured in the photon energy range of interest with synchrotron radiation.

Subtracting Interferences in X‐Ray Spectra Obtained With Grating Spectrometers

X-Ray Spectrometry, EarlyView.
ABSTRACT Higher order diffraction from surface contamination poses a major challenge for soft x‐ray spectral analysis using reflection zone plate spectrometers in electron probe microanalysis. We developed two correction methods applied to the Al L2,3 and Zn M2,3 emissions in AlZn60 alloy spectra: sequential overlay and subtraction of C Kα and O Kα ...

Crystal Structure of [Sr(SeC2H)2(NH3)2], Solved and Refined From Powder X‐Ray Diffraction Data

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
The synthesis and crystal structure of [Sr(SeC2H)2(NH3)2] are described, the first alkaline earth metal compound with the recently discovered –SeC2H anion. The title compound releases NH3 even under ambient conditions, so its crystal structure had to be determined from moderately resolved X‐ray powder diffraction data.

More π, less Gap: Band Gap Tuning in Hybrid Antimony Halide Charge Transfer Semiconductors

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
Extending the π‐conjugation of the organic cation from bipyridinium to phenanthrolinium in hybrid antimony chloride charge transfer semiconductors reduces the band gap from 2.6 to 2.1 eV. This demonstrates that modifying the organic cation's π‐system enables band gap tuning in hybrid charge transfer semiconductors.
