在实验室中使用激光产生的等离子体源在软X射线范围内进行近边X射线吸收精细结构(NEXAFS)光谱是可行的。我们提出了一项使用七种不同目标材料进行优化数据分析的研究。原子序数从Z=6到Z=79的材料的发射光谱显示出明显的差异，这使得为专门实验选择合适的靶材料是可行的。对于NEXAFS光谱，以112.5 nm厚的聚酰亚胺薄膜为参照，说明了类连续发射光谱的优越性。
Near edge X-ray absorption fine structure (NEXAFS) spectroscopy in the soft X-ray range is feasible in the laboratory using laser-produced plasma sources. We present a study using seven different target materials for optimized data analysis. The emission spectra of the materials with atomic numbers ranging from Z = 6 to Z = 79 show distinct differences, rendering the adapted selection of a suitable target material for specialized experiments feasible. For NEXAFS spectroscopy a 112.5 nm thick polyimide film is investigated as a reference exemplifying the superiority of quasi-continuum like emission spectra.
