State-Dependent Partial Fluorescence Yield

The use of inverse partial fluorescence yield allows obtaining spectra free from saturation effects, but it does not allow investigating or quantifying the non-radiative decay at the L-edge of transition metals. Resolving this issue could be realized by discriminating between the various fluorescence contributions, in particular that of oxygen Kα from those of the metal L-edges and between the different L-edge contributions themselves. Such a method was recently developed and combined with the liquid micro-jet technique and named state dependent partial fluorescence yield (SD-PFY).


SD-PFY contributions from different transitions are separately integrated in order to obtain FY spectra from specific states. For separating the different photon energies, an XES spectrometer in Rowland-circle design can be used. Figure taken from the review of Lange et al.
