We present valence-to-core x-ray emission spectroscopy of Ti, TiO and TiO2 by means of a double crystal von Hamos spectrometer based on full-cylinder highly-annealed pyrolytic graphite mosaic crystals. We demonstrate that, using a double crystal configuration, an energy resolution of E/ΔE ≈ 2700 can be achieved in a compact setup using cylindrically curved optics with a radius of curvature of 50 mm. The stated energy resolution proved to be high enough to identify and determine chemical shifts of the Kβ2,5 and Kβ" emission lines of both oxides. The experimental results are supported by calculations with the ab initio package OCEAN and compared to literature values.

通过双全圆柱晶体 von Hamos 光谱仪对 Ti、TiO 和 TiO2 进行价核 X 射线发射光谱

我们通过基于全圆柱高度退火热解石墨镶嵌晶体的双晶 von Hamos 光谱仪展示了 Ti、TiO 和 TiO2 的价核 X 射线发射光谱。我们证明,使用双晶体配置,可以在使用曲率半径为 50 mm 的圆柱弯曲光学器件的紧凑设置中实现 E/ΔE ≈ 2700 的能量分辨率。事实证明,所述能量分辨率足够高,可以识别和确定两种氧化物的 Kβ2,5 和 Kβ" 发射线的化学位移。实验结果得到了 ab initio 包 OCEAN 的计算的支持,并与文献值进行了比较。
