摘要
通过引入细像素级CMOS探测器,测试了商用软x射线发射光谱仪的改进。Mg - k - α-发射峰宽减小到现有CCD探测器的1/4。此外,还观察到Mg和MgO的Kα-和k β-发射谱线能量位置的差异。MgO的O - k发射谱显示出一些反映化学键态的结构。该光谱仪可以很容易地分辨出Fe、FeO、Fe3O4和Fe2O3中Fe原子的化学键态的Lα、β-发射强度谱。
High energy-resolution soft X-ray emission spectrometer using a back-thinned CMOS detector for chemical bonding state analysis.
Improvement of a commercially available soft X-ray emission spectrometer was tested by introducing a fine-pixel-sized CMOS detector. The peak width of Mg Kα-emission was reduced to 1/4 of that obtained by the CCD detector presently used. Furthermore, the differences in the energy positions of satellite lines of Mg Kα- and also Kβ-emission profiles of Mg and MgO were observed. O K-emission profile of MgO exhibited a few structures reflecting the chemical bonding state. This spectrometer easily discriminated the intensity profiles of Fe Lα,β-emission reflecting the chemical bonding states of Fe atoms in Fe, FeO, Fe3O4, and Fe2O3.
