Paper Abstract

Laser pulses can probe any material, even the more chemically refractory ones. The scaling to ever smaller material sizes demands the utilization of lasers well below commercially available UV lasers, e.g. excimers or frequency quadrupled/quntipled Nd:YAG. While using plasma-driven XUV lasers, the drastic reduction of sampled volume is not accompanied by a reduction in sensitivity, which indicates an enhancement of the sample utilization efficiency using XUV. A capillary discharge Ne-like Ar laser operating 46.9nm was utilized demonstrating unprecedented insights. The rapid direct and absolute characterization in 3D of the elemental distribution using XUV laser – mass spectrometry is shown here in the case of solar thin films. Elements such as suphur, zinc and selenium showed similar layered concentration, while sodium, calcium, and silicon may have diffused from the soda-lime glass substrate. Lithium was doped, and is responsible for the development of a granular porous fabric.
