Direct comparison of the x-ray emission and absorption of cerium oxide

Abstract

X-ray emission spectroscopy and x-ray absorption spectroscopy have been used to investigate the photon emission and absorption associated with the Ce 3d5/2 and Ce 3d3/2 core levels in Ce oxide. A comparison of the two processes and their spectra will be made.

Pre-eminence of the Indirect Channel in the Resonant Inverse Photoelectron Spectroscopy of Cerium Oxide

“…(Top) The XAS of cerium metal, cerium oxide on cerium metal and reference spectra of a thin film of cerium oxide [2]. The instrumental broadening of the XAS is on the scale of 0.1 eV to 0.2 eV, allowing for the observation of substantial fine structure.…”

“…The XAS measurements were made on Beam-line 8 at the Advance Light Source (ALS) at Lawrence Berkeley National Laboratory (LBNL), in Berkeley, CA [2]. As discussed in detail in Reference 1, the stoichiometry of the cerium oxide is unknown.…”

“…Three particularly important variants are inverse photoelectron spectroscopy (IPES) [1], X-ray emission spectroscopy (XES) [1], and X-ray absorption spectroscopy (XAS) [2]. Examples of the data for each are shown in Figure 1.…”
